Pushbutton Indicator and Contactor

NCH8-□M series Manual Modular AC contactor (here in after referred as contactor) is mainly used in power systems with AC 50Hz/60Hz, rated operating voltage up to 400V and rated operating current up to 63A. It is used as remote or manual switch for circuit control under AC-7a and AC-7b (non-inductive load or low-inductive load/resistance furnace,domestic appliance and low-inductive load of similar applications) application category. The contactor shall not be used for breaking short-circuit current, therefore it should be used with a proper short-circuit protection device. CATALOG EN NCH8-□M PDF
