6 FAQs about Rcb circuit breaker in China in Uk

What is a RCBO circuit breaker?

Available in 2 or 4 pole and in current ratings from 25A to 125A. 6kA and 10kA Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) combine the functionality of a RCCB and MCB in one device, protecting against residual current (earth leakage) faults as well as overcurrent and short circuit protection.

What is an RCBO & how does it work?

RCBOs are residual current circuit breakers with over current protection. Effectively, an RCBO is a unit that combines an RCD (Residual Current Device) and MCB (Miniature Circuit Breaker). Find out more in our comprehensive RCBOs guide. RCBOs combine overload and short circuit protection with protection against earth leakage currents.
