AM1L Series Earth Leakage Circuit Breaker

Poles:3, 4. Rated insuiating voltage:500V,800V. Rated operating voltage:400V. Rated current:10~630A Certificate:CCC 1.Application 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 manufacturing 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 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 GeneralIEC60947-2 and GB 14048.2 Low voltage breakersIEC60947-4 and GB 14048.4 Contactors and motor startersIEC60947-5.1 and GB 14048.5 Electrical equipments of electromechanical control circuit 2.

Note: According to the pole number of product, it calssifies three and four poles. The neutral pole (N-Pole) of the four-poles products has four types: Type A: N-pole without over-current release unit, it has been connected all the time, not closing and opening with the other three poles.Type B: N-pole without over-current release unit, which closing and opening with the other three poles. Type C: N-pole fixed with over-current release unit, which closing and opening with the other three poles. Type D: N-pole fixed with over-current release unit, it has been connected all the time, not closing and opening with the other three poles.1. The limiting breaking and arc-over distance includes horizontal and vertical installation.2. If the three-pole breaker of this series is connected with three phase load, the load can not have neutral line, otherwise the breaker will have fault action.3. Protection Characteristic The thermal release of the breaker has again-time-limit property; the electromagnetic release is inst. Operation, its property see table 2(for distribution),table 3 (motor protection).
