RESIDUAL CURRENT CIRCUIT BREAKER|
SAFETYTM RESIDUAL CURRENT CIRCUIT BREAKER provides protection against the dangers due to an earth-fault condition and therefore reduce the risk of fire and/or electrocution by limiting the flow of current through an earth fault.
The SAFETYTM RCCB has a measuring system consisting of a summation current transformer with a permanent magnetic tripping device. In a normal healthy circuit, the current detected by the summation current transformer is zero. When there is a current flowing to the earth due to a fault, this will be registered by the summation current transformer which will cause the RCCB to trip once the leakage current exceeds a predetermined value.
