Chint ContactorsThe purpose of use 1. 1 NCH8 M series Manual Modular AC contactor (here inafter 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 7b and AC 7a (non inductive load or low inductive load resistance furnace, domestic appliance and low inductive load of similar applications) application

1. The purpose of use
   1.1 NCH8-□M series Manual Modular AC contactor (here inafter
   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-7b and AC-7a
   (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.
