What are RCBO used for?

RCBOs are commonly used in applications where there is the need to combine protection against overcurrents (overload and short-circuit) and protection against earth leakage currents. RCBOs help in sen

RCBO

An RCBO is a residual current circuit breaker with overcurrent protection and monitors electrical circuits to keep them running safely, disconnecting the circuit if it's unbalanced. These devices are

What is difference between RCD and RCBO?

What is difference between RCD and RCBO?

Whereas an RCD is designed solely to protect against earth leakage and an MCB protects only against over-current, an RCBO protects against both types of fault.
