[mebaelectric]

RCBO Ensures Electrical Safety in Your Home

A sophisticated electrical safety device, RCBO Residual Circuit Breaker, guards against fault currents as well as overcurrents by keeping an eye on the current flowing through a circuit. It accomplishes this by spotting electrical current imbalances and quickly cutting the circuit when a problem is found, greatly lowering the possibility of electric shock and fire.

How Do RCBOs Operate?

Finding Residual Current: The live (phase) and neutral wire balance of a circuit is continually monitored by the RCBO. An appliance's input current and output current are equal in a healthy circuit. An imbalance results when a human unintentionally touches a live component because part of the current passes through it and down to the ground, lowering the returning current. This imbalance is frequently detected by the RCBO in milliseconds, at which point it trips, turning off the electrical supply and averting major harm or death.

Protection against Overcurrent: Short circuits and overloads can result in overcurrent. To reduce the risk of fire dangers and potential damage to appliances and wiring, the RCBO recognizes these situations and disconnects the circuit. The RCCB Circuit Breaker is also vital.

Why Do RCBOs Matter?

Safety: An RCBO's main function is to offer a high degree of protection against the possibility of fire and electric shock. It guarantees occupant safety by identifying fault currents and overloads.

Cost-effectiveness and Convenience: By combining the functions of an MCB with an RCD, RCBOs save installation costs and the requirement for separate devices, freeing up space in the consumer unit (fuse box).

Compliance: To fulfill electrical safety requirements, several areas have legislation requiring the installation of RCBOs in new construction and during significant modifications.

Establishment and Upkeep

Even though RCBOs are sturdy and dependable, a trained electrician should always perform their installation and maintenance. When an RCBO from RCBO Circuit Breaker Manufacturer is installed correctly, it is guaranteed to be appropriately rated for the circuit it guards, improving safety and adhering to regional electrical codes. As advised by the manufacturer, routine inspections and testing are essential to preserving their protective qualities over time.

Empower Your Electrical System: MCB, RCCB, and Electric Panel Boards

Circuit breakers are basically safety devices for anything that uses electricity. These fixtures, which are made of reusable and high-temperature resistant material, guard the dangerous electrical circuit ends. MCB, MCCB, RCCB, RCCD, and RCBO are all types of circuit breakers for electricity systems. They are used in homes to protect people against hazards and appliance damage. 

Let’s understand the importance and uses of different circuit breakers in electricals.

Different Circuit Breakers of Electricals

The design of the devices involves performing specific functions. MCB and RCCB are used for small-sized devices with a small current that is not more than 125 amps. MCCBs are used for high currents up to 100 amps.

Safety and efficiency are the most important aspects. Three essential components play an important role in achieving this:

Miniature Circuit Breaker (MCB)

Residual Current Circuit Breaker (RCCB) 

Electric Panel Board 

Being able to understand and give attention to the key elements of these circuit breakers is of extreme importance for households, offices and industries in ensuring a safe, functional and secure environment. 

Miniature Circuit Breakers (MCB)

MCBs, or Miniature Circuit Breakers, serve as automatic switches that interrupt the flow of electricity in case of overcurrent or short circuit conditions. This feature reduces the chance of damaging some household appliances such as electric irons, wiring, and fires. MCBs are electromechanical devices that are fundamental for the safety of electrical circuits. Their main function is to protect electrical circuits, appliances, and wiring from damage and fire hazards. 

Importance and Uses 

Overcurrent Protection: The MCBs detect a high current flow, which trips down the power supply, thereby preventing electrical appliances from overheating.

Short Circuit Protection: In the cases of a short circuit, MCB manages to cut off the broken part of the circuit, so fires that electrical devices create are difficult to occur.

Tripping Mechanism: MCB has thermal or electromagnetism for the detection of abnormal currents and trip accordingly.

Resettable: Rather than depending on the concept of manual reset, unlike fuses, MCB can be easily reset manually after tripping, therefore leaving the protection on.

Residual Current Circuit Breakers (RCCB)

RCCBs, also called residual current devices, are meant to offer electrical safety. Although MCB works to watch out for overcurrent and short circuits, the RCCB performs a specific function, identifying leakage currents, especially the ones caused by electric shocks.

Importance and Uses

Leakage Current Detection: RCCB  always ensures a steady supply because they continually monitor the imbalance of currents flowing in and going out. Leakage of the current is detected immediately. They react within a second on the detection of a fault, disconnecting the circuit from the inside to the outside.

Protection Against Electric Shock: RCCB cut off power at the speed of seconds after getting to know electric current leakage. They minimise the risk of electrocution and protect people from being exposed to an accident.

Sensitive Operation: RCCB operates with high sensitivity. They ensure that even the smallest leakages are detected, even as low as a few milliamperes.

Electric Panel Boards

Electrical panel boards (also known as circuit breaker panels, distribution boards, or load centres) are the power distribution sources for all the electrical components in a building. They serve as a central hub for distributing electricity throughout a building or facility. It houses protective devices such as MCBs and RCCBs and facilitates organised and safe electrical distribution by distributing power from the main supply to various circuits within the building. 

Importance and Uses

Circuit Distribution: The electric panels boards are usually installed near the main electricity distribution systems, and they are designed to distribute electrical power coming from the main panel to different circuits within a building so as to ensure both balanced and efficient power distribution.

Protection Devices Integration: Most MCB/RCCB are generally found within electric panel boards, which act as a common source of protection from overcurrents, short circuits, and electric shocks.

Organization and Accessibility: The electrical Panel board facilitates the organisation of electrical current, which makes it easier to find and take care of the individual circuits. Moreover, they allow maintenance actions to be performed and provide easy access in case of maintenance and troubleshooting.

Conclusion

It is important to understand the role and functions of MCB, RCCB, and Electric Panel Boards in order to avoid electrical hazards and to ensure the proper functioning of the electrical system. Whereas MCB eliminates overcurrent and short circuits, RCCB is installed to detect leakage current that would cause electric shocks. 

Such electrical supplies must be well-stocked and from LnTSufin to meet your electrical system requirements.

How does short circuit protection work?

People have electrical circuits in their home that provides electric current to the charged particles like generators, batteries, etc. A short circuit happens when electricity finds a shorter, unintended path to flow through instead of following the designated wires. This can allow excessive current flow through the circuit causing multiple problems, such as;

This sudden change creates several problems:

Too much electricity

Heat and sparks

Tripped breakers

In simple words, a short circuit can cause various problems like overheating, sparks, and even fires. So, it is crucial to know the cause of short circuits which can be a faulty wire or damaged appliances. Also, take necessary steps to guard them to prevent fire. In such conditions, you will require a short circuit protection device to protect your electric devices from overcurrent.    

Why are circuit protective devices important?

Short circuit protection devices play a crucial role in protecting electrical systems. They prevent high fault currents from flowing during electrical faults that not only safeguard the installation but also prevent harm to consumers. Circuit breakers or fuses offer overcurrent protection by automatically disconnecting the supply when there's an overload or fault current. As we discussed above, overloads happen when there's a faulty item or too many devices connected to a circuit. On the other hand, short circuits occur when a live wire touches an exposed part or another wire with low resistance. It happens often due to wiring errors or cable damage. Similarly, Earth faults occur when a live wire touches an earthed conductor or exposed part, though, they do not involve high current flow.

Therefore, you must have an appropriate circuit protection, installed to ensure your safety.

What are the different types of circuit protection?

A fuse is a safety device that contains a piece of wire that melts easily. If the current passing through the fuse becomes too high, the wire heats up until it melts, breaking the circuit. It stops the current flow immediately.

There are different types of fuses available:

●      BS3036 rewirable fuses:

These are commonly found in domestic circuits. They are affordable, easy to repair, and simple to check. However, there are chances of their misuse by an incorrect fuse wire making them too hot.

●      BS1361/1362 cartridge fuses:  

These are used in plug tops and distributions. Cartridge fuses are relatively accurate as they have a low fusing factor, and are easy to replace. However, they are more expensive than reusable fuses.

●      BS 88 High Breaking Capacity Fuses (HBC):

Normally, people use them in industrial setups and motor circuits. You can operate & replace them easily. However, they are costly to replace due to not having external arcing.

Residual Current Devices (RCDs) can detect and disconnect the power supply in case of an earth fault. For example, when a live wire touches an earthed equipment case or when a live wire is cut. These faults can lead to electric shocks and fires, so RCDs are crucial safety devices.

A Miniature Circuit Breaker (MCB) is another safety device that protects electric circuits from overcurrent. Unlike fuses, MCBs are reusable and easier to use. Since they have an on/off switch for circuit isolation, they are safer because the conductor is enclosed within a plastic casing. However, they are more expensive than fuses requiring regular testing.

Circuit breakers act as switches and open when there's excessive current flow. Professionals can reset them without damage in case of overheating. MCBs alone don't protect against electric shocks caused by earth leakage. Short circuit protection device manufacturers suggest using Residual Current Devices (RCDs) and Residual Current breaks with Overcurrent (RCBOs). The combination of the three can protect against overcurrents and earth leakage current faults.

2. Có mấy loại aptomat chống giật? 

một. Có mấy loại aptomat chống giật 

Aptomat chống giật được chia ra các loại cơ bản sau đây.

Cầu dao tự động chống giật dạng tép RCCB (Residual Current Circuit Breaker). 

Aptomat chống giật khối dạng có bảo vệ quá tải ELCB (Earth Leakage Circuit Breaker).

Aptomat chống giật dạng tép có bảo vệ quá tải RCBO (Ngắt mạch dư với bảo vệ quá dòng).

b. Aptomat select chống giật 

Nên chọn Aptomat ưu tiên chống giật có chức năng bảo vệ quá tải (RCBO, ELCB) thay thế aptomat thường. 

Đối với Aptomat chỉ có chức năng chống giật (RCCB) bắt buộc phải lắp MCB.

Select Aptomat chống giật theo số pha / số cực

Lựa chọn Aptomat chống giật 3 pha (3 cực) lắp cho hệ thống 3 pha tải hợp (tải 1 pha, 3 pha, sử dụng trung tính) vì sẽ khiến Aptomat chống giật bị nhảy.

3. Chức năng của Aptomat chống giật:

RCBO được kết hợp giữa RCCB và MCB trong điện thiết bị. RCBO thường được sử dụng với dòng điện định mức là 30mA. Aptomat chống giật FUJI có một vô số trò chơi cùng quan trọng đó là được sử dụng để ngắt điện khi gặp sự cố về đường thẳng hoặc là điện áp quá tải, nhằm mục đích phục hồi trạng thái bị tắt điện.

Aptomat chống giật 1 pha: nó so sánh dòng điện chạy qua 2 dây mát và lửa, nếu dòng điện này khác nhau quá một ngưỡng rò nhất định thì nó sẽ ngắt điện khỏi tải, không cho tải làm việc nữa.

Aptomat chống giật 3 pha: nó so sánh dòng điện chạy qua 3 dây pha và dây trung tính, nếu dòng điện này khác nhau quá một ngưỡng rò nhất định thì nó ngắt.

4. Cấu tạo Aptomat chống giật RCBO và nguyên lý hoạt động:

Cấu tạo Aptomat chống giật 

Cấu tạo Aptomat chống giật 

Nguyên lý hoạt động

Aptomat chống giật thiết kế cho 2 dây nóng và dây nguội của dòng điện đi qua 1 cuộn cảm. Đây giống như 1 biến thế thông thường với cuộn sơ cấp 1 vòng dây (chính là 2 dây mát và lửa đi qua tâm biến thế) và cuộn thứ cấp có vài chục vòng dây.

Aptomat chống giật 1 pha:

Hai dây mát và nóng đi qua 1 biến dòng có lõi sắt hình xuyến và cuộn thứ cấp. Dòng điện sẽ đi ra ở dây nóng và về tại dây mát và ngược lại. Khi 2 dòng điện bằng nhau từ trường sẽ tự biến thiên và điện áp ra cuộn thứ cấp  = 0. Khi điện áp 2 dòng khác nhau sẽ sinh ra từ trường biến thiên khác nhau, cuộn thứ cấp xuất hiện dòng điện cảm ứng và được đưa vào IC để kiểm tra sự an toàn.

Aptomat chống giật 3 pha:

Ở Aptomat chống giật 3 pha dòng điện sẽ tuyền ra tại dây nóng và về ở dây mát và ngược lại dẫn đến dòng điện ngược chiều nhau. Từ đó, từ trường biến thiên tại lõi sắt của biến dòng có chiều ngược nhau. Khi 2 dòng điện có giá trị bằng nhau thì từ trường biến thiên sẽ tự diệt lẫn nhau khiến điện áp ra cuộn thứ cấp của biến dòng = 0. Khi  2 dòng điện có giá trị khác nhau thì từ trường cũng sẽ khác nhau khiến dòng điện cảm ứng xuất hiện trên cuộn thứ cấp biến dòng. Sau đó được đưa vào IC để kiểm tra.

Why is Circuit Protection Important? Panasonic Electronic Components distributors

All the appliances that we are using for heating, lighting, etc have electrical circuits. Electricity from power stations is being provided to them via various transmitters and distribution networks.

Circuit Protection is necessary because it protects you and your property in case of an electrical fault. In case, there is a short circuit or faulty wiring, there is a high risk of injury.

All these electrical circuits have maximum limits for the current which in the case that exceeds their limit, causes overheating, which can cause fire to break out.

How does Circuit Protection work?

Circuit protection is basically ensured by tripping the circuit.

The supply of electricity is cut off to that distinct circuit automatically.

Cutting off electricity prevents the wire from overheating and potentially causing fire and other hazardous situations.

Circuit Protection Devices

Fuses: Fuses are the most traditional method of circuit protection. They need to be replaced whenever the fuse ‘blows’.

Miniature Circuit Breaker: MCBs or Miniature Circuit Breakers are modern Circuit Protection devices. Unlike fuses, there don’t need to be replaced after they drip down but simply turn up to restore the power.

Residual Current Devices: RCDs or Residual Current Devices stop the electrical current when identifying an abnormality in its flow. The advantage RCDs have over MCBs is that they can be used for more than one circuit.

Residual Current Breaker and Overload Protection: RCBOs or Residual Current Breaker and Overload Protection are essentially a combination of RCDs and MCBs. They offer the maximum level of circuit protection.
