GTM1L Series Earth Leakage Circuit Breaker

Item Name: GTM1L series Earth Leakage Circuit Breaker

GTM1L series earth leakage circuit breaker are one of the new type earth leakage breakerswhich have been developed by the company using international advanced design and manufacturingtechnology. Suitable for a line of AC50Hz/60Hz, rated voltage up to 400V, rated current16A to 630A. And is acted as infrequent changeover of circuit or infrequent starting of motor. Thebreaker has overload, short-circuit and under-voltage protective function, which can protect thecircuit and the power equipment against damage, meanwhile, it can provide protection to thesefire dangers that caused by these long-time existed grounding fault that can not be detected bythe over-current protection.

This breaker can be installed vertically(upright) or horizontally(transverse). Wiring of the breaker can not be in adverse direction, that means power supply line must beconnected to terminal 1, 3 and 5, and the load line connected to terminal 2, 4 and 6. The rated residual operating current I_n and the maximum breaking time can be adjustedon site according to practical condition.

The leakage protection module still can work normally when the phase voltage reduce to 50V. It has the same overall size with the GTM1L series breakers, which make the installation moreexchangeable.
