MEH8-25M Modular Contactor (also known as analog contactors and architectural contactors) are mainly used in power systems with AC 50Hz/60Hz, rated working voltage up to 400V and rated working current up to 100A. They are used as remote switches and control circuits in AC-1 and AC-7a (non-inductive or low-inductive loads, resistance furnaces, household appliances and similar low-inductive loads). It can also be used to control the load of household motor. Modular Contactors cant't be used in break short-circuit currents, so appropriate short-circuit protective appliances (such as small circuit breakers) should be selected when using them. BCH8 Modular Contactor are mainly used in homes, hotels, apartments, office buildings, public buildings, shopping malls, gymnasiums and other places to achieve automatic control functions.
