What is the RCBO?

RCBO is basically known as residual current circuit breaker with overcurrent. And residual current circuit breaker with overcurrent is a kind of low-voltage circuit breaker. RCBOs are used to protect against earth leakage fault currents with over currents. RCBO has extra protection against overload and over current. And it mainly uses a microcontroller and it can also be called as a combination of MCCB and RCCB. That is why; It is more useful than the RRCB; Because RCCB does not provide protection against overcurrent. Some RCBO have indicators to indicate any earth fault. This feature is very useful as it helps the engineer quickly in troubleshooting.
