RCBOs

RCBOs are a type of residual current circuit breaker, a safety device for monitoring power distribution and providing protection. They’re often found in a fuse box, consumer unit or breaker panel. RCBOs combine the functionality of an RCD (Residual Current Device) and MCB (Miniature Circuit Breaker) in one.

What Do RCBOs Do?


The primary function of an RCBO is to ensure the safe operation of electrical circuits. They can monitor electrical currents and come with overcurrent protection in case of an overload. RCBOs can disconnect the entire circuit when there is a problem. This safeguards against earth leakage currents and short-circuiting.

What are the Different Types of RCBOs?


RCBO stands for Residual Current Circuit Breaker with Overload protection. There are different amp ratings, phases and curve types for various applications.

How is RCBO Different From RCD?


An RCD is a Residual Current Device. It safeguards against faults, residual currents and electric shocks. RCBOs can do all this, and they can also protect against overload and short circuits.
