DCH8 Modular Contactor With the new generation of technical platform and automatic production and testing equipment,the new DCH8 modular contactor fits the customer application needs which is in a good quality. DCH8 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. DCH8 Modular Contactor are mainly used in homes, hotels, apartments, office buildings, public buildings, shopping malls, gymnasiums and other places to achieve automatic control functions.
