Thermal-magnetic residual current circuit breaker RDM67L

overcurrentearth-leakageresidual current

RDM67L series residual current circuit breaker,is applied to distribution network of AC50Hz,rated operate voltage 400V,rated operate current up to 800A for protecting people indirectly touch, and circuit transferring,motor starting unfrequently. And it has overload long-delay inverse time limit,short-time instantaneous and undervoltage,and residual current protect function,to protect circuit and equipment. This circuit breaker has the advantages of compact volume, high-breaking capacity,short-arc. This circuit breaker has isolate function. This circuit breaker shall no change the input direction, N,1,3,5 terminal shall connect power side, 2,4,6,N shall connect load side. This circuit breaker conforms to standards of IEC60947-2. 3.0perate,install and transportation condition 3.1 - Temperature: Max +40C, Min +35 C.Day average shall no more than +35C 3.2 - Altitude:Max 2000, 3.3 - Humidity: At +40 C,humidity max reach 50%.But the higher humidity can be allowed at lower temperature. For instance,90% is acceptable at +20 C.And the condensation should be taken care at temperature changing. 3.4 - Pollution level:3 Level 3.5 - Install location:medium without métal corrosion and insulation damage gas and conduct dust, and also no impact and rain water influence, tilt between Install plate and each direction shall no more than 5°. 3.6 - Install external magnetic field shall no more than 5 times of ground magnetic. It is suitable for B type electromagnetic environment.
