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.
