Item Name: GTM2L series Earth Leakage Circuit Breaker
GTM2L 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. 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.
Standards:
IEC60947-2 and GB 14048.2
