In addition to other protective components.Under the condition of RCCBs on-off capacity rating only up to 80 A.In conclusion RCCBs only leakage protection and rated load current on and off.
With over-current protection of residual current circuit breaker.It is the Residual Current management circuit-Breakers with Integral Overcurrent protection.

ETEK's RCBO function:Protection of short-circuit protection,excessive protection andLeakage protection.
Residual current circuit breaker module RCCB,the full name of this is the "Residual Current" Circuit-Breakers.
