The DZ leakage series is in mode of current operating, mainly composed by current senser, electronic units board, leakage release and breaker which have protection device of overload and short-circuit. All of the parts are installed in the moulded case. When leakage and body shock happen in the protect circuit line, reach the value of rated leakage operating current, a signal can be send and amplified from the current transformer to the electronic board. Leakage release cut off the power supply to promise the safety.

In the situation of the rush voltage 6000V, the breaker can work in normal.
