AM1L Series Earth Leakage Circuit Breaker

AM1L-100M/4P

1. Application and Description
   AM1L series earth leakage circuit breaker are one of the new type earth leakage breakers which have been developed by the company using international advanced design and manufac-turing technology. Suitable for a line of AC50Hz/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 breaker has overload, short-circuit 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 can not be detected by the 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 be connected to terminal 1,3 and 5,and the load line connected to terminal 2,4 and 6.
   The rated residual operating current I Δ n and the maximum breaking time can be adjusted on 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 AM1 series breakers, which make the installation more exchangeable.
   The breakers are suitable for isolation, its symbol are:

   The breakers comply with the demands of the following standards:
   IEC60947-1 and GB/T 14048.1 General
   IEC60947-2 and GB 14048.2 Low voltage breakers
   IEC60947-4 and GB 14048.4 Contactors and motor starters
   IEC60947-5.1 and GB 14048.5 Electrical equipments of electromechanical control circuit
