What are RCBOs and what does rcbo stand for
What are RCBOs ？RCBO meaning is Residual Current Breaker with Overcurrent. RCBO breaker offers dual protection from electrical shocks and potential fire risks due to overloads and short circuits. In this article we will talk about what is rcbo in electrical and what does an rcbo do.
The acronym “RCBO” stands for Residual Current Breaker with Overcurrent. The “residual current” segment points to any current potentially seeping from an electrical circuit, while the “breaker with overcurrent” segment relates to the device’s capacity to cut off or disconnect a circuit if the coursing current exceeds safety thresholds.
What is rcbo in electrical
RCBO circuit breaker can prevent electrical circuits from electrical shocks and fire risks in residential and commercial buildings.rc bo is designed to safeguard against two electrical fault categories: residual current faults and overcurrent faults, they bring together the operations of two essential devices: an RCD (Residual Current Device) and an MCB (Miniature Circuit Breaker).
- Residual Current Detection:The RCBO continuously monitors the balance of current between the live and neutral wires.If it detects an imbalance that suggests a leakage current (typically 30 milliamperes or more), it quickly disconnects the circuit. As a rusult, the rcbo help prevent electrical shocks and fires.
- Overcurrent Protection: In addition to residual current detection, RCBOs also provide overcurrent protection. This is where the “Breaker with Overcurrent” part comes in. When the current exceeds a predetermined safe level (the ‘rated’ current), the RCBO ‘trips’, or switches off, automatically. This can protect the wiring and devices on the circuit from overheating and potentially causing a fire. Once the overcurrent issue has been resolved, the RCBO can be manually reset and the circuit can be safely used again.
Picking the Suitable RCBO for Domestic Utilization
For domestic use, different requirements can choose different circuit breaker.
If the purpose is to protect the circuit from overload or short circuit. You can choose MCB or RCBO. The RCDBK offers a variety of models with different specifications of MCB and RCBO. For RCBO, we recommended 6A,10A, 16A, 20A，25A and 40A. with a residual current sensitivity of 30mA. Meanwhile, if choose MCB, types B, C, and D, and a 2-pole configuration, which may suit a variety of household circuits。
However, the target function is leakage protection. Then RCCB or RCBO has this function. You can choose 1P+N poles and residual current sensitivity of 30mA of rccb or rcbo breaker.
In addition, if the aim is protecting against overcurrents (overload and short-circuit) and earth leakage currents. The wise choice is rcbos. Firstly, lighting circuits may require RCBOs with a rating of 6A or 10A. Secondly, socket circuits could demand 16a rcbo or 20a rcbo. After that, to high-power appliances, such as electric stoves or washing machines, these may necessitate 32 amp rcbo or higher.
For households,it’s recommended to use a high-sensitivity leakage protector with a leakage current of 30mA. This is because 30mA is considered to be a suitable and safe leakage protection circuit breaker for household use. Therefore, the 30mA specification is often considered the best balance between safety and functionality.
In Conclusion of what are RCBOs
RCBOs are essential components in contemporary electrical safety. They integrate the advantages of RCDs and MCBs, offering comprehensive protection against both electric shocks and fire risks due to electrical malfunctions. While this guide provides a robust understanding of RCBOs, always enlist the assistance of a professional electrician when interacting with electrical systems.
