Earth Leakage Circuit Breaker

Basic Info

Model No.: 117

Product Description





1. Application and description

TFCM1LEseries earth leakage circuit breaker are one of the new type earthleakage breakers which have been developed by the company using international advanced design and manufacturing technology. Suitable for a line of AC 50Hz/60Hz, rated voltage up to 400V, rated current 16A to 630A. and is acted as infrequent changeover of circuit or infrequent starting of motor.The breake has overload, shortcircuit and under-voltage protective function, which can protect the circuit and the power equipment against damage, meanwhile, it can provide protection to these fire dangers that caused by these long-time existed grounding fault that cannot be detected by the overcurrent protection.
