TXM1L molded case earth leakage circuit breaker is designed for electricity circuit with rated frequency of 50/60Hz, rated voltage of 400V and rated working current of up to 630A to protect the circuit from damage caused by overload or short circuit. Meanwhile, it can protect people from hurt caused by earth leakage shock. Also it can act as un-frequently switch in power distribution.
Based on the difference of rated ultimate short-circuit breaking current (Icu), TXM1L molded case earth leakage circuit breaker can be classified into two classes: M (relatively high breaking capacity) and H class (high breaking capacity).
