M1L Earth leakage protection case breakers mccb 10A~600A high breaking capacity electric moulded case circuit breaker

GTM1L series earth leakage circuit breaker is a new type of circuit breaker that adopts international advantage design and technology . The breaker is mainly used in distribution network of AC50Hz , rated voltage 400V and below , rated operating current up to 630A . The breaker protects circuit and supply device from overload , short-circuit and under-voltage . It also protects from fire disaster cased by earthing fault.

   Code switch position for leakage operating current:

Note : 1. limit breaking capacity and arcing distance including horizontal and vertical level installation.
2. When GTM1L series3 pole breaker connecting 3 phase overload , overload can not includingn eutrall ine, otherwise the breaker will make malfunction.
3. When GTM1L serise 3 pole breaker connecting one phase overload , phase line connects left pole , neutral line connects right pole don't connect middle pole.
