400V,4P Residual Current Circuit Breaker with Test Button for Regular Inspection. Simple and robust operating mechanism
A residual current circuit breaker (RCCB), is an device that disconnects a circuit whenever it detects that the is not balanced between the energized conductor and the return conductor. Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit.
RCCBs/ RCDs are designed to quickly enough to mitigate the harm caused by such shocks although they are not intended to provide protection against overload or conditions.
Features:
Simple and robust operating mechanism
Rotary handle with on/off indication
Dual termination for bus bar as well as cable connection
Test button for regular inspection
