Residual Current Circuit Breaker

The Residual Current Circuit breaker RCCBs are the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric shock caused by indirect contacts.

UNION provides precisize and safe RCCBs from 30mA to 300mA leakage currents. RCCBs are widely used together with MCBs. Rated current varies from 16A to 100A with magnetic and electronic trip unit options.
