Leakage switch DZ20L-160

Detailed Product Description


The DZ20 moulded case circuit breaker switch leakage series are new model which developed upon the DZ20 MCCB series. They are 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.
