Application

AM1L series earth leakage circuit breaker is one of the new type earth leakage breakerswhich has been developed by the company using international advanceddesign and manufacturing technology.Suitable for a line of AC50/60Hz,rated voltage up to 400V,rated current 16Ato 630A.and is acted asinfrequently changeover of circuit or infrequent starting of motor.The breaker has overload,short-circuit and undervoltage protective function,which can protect the circuit and the power equipment against damage,meanwhile,it can provide protection to thesefire risk that caused by these long-time existed grounding fault that can not be detected by theover-current protection. This breaker can be installed vertically(upright)or horizontally(transverse). The wiring of the breaker can not be in adverse direction,that means power supply line mustbe connected to terminal 1,3 and 5,and the load line connected toterminal 2,4 and 6. The rated residualoperating currentI△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 reduced to 50V.It has the same overall size withthe AM1 series breakers,which make the installation more exchangeable. The breakers comply withthe demandsof 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 startersIEC60947-5.1 andGB 14048.5 Electrcal equipmentsof electromechanical control circuit
