CHINT NC7 series AC contactor,
The NC7 series AC contactor (hereinafter referred to as “contactor”) is mainly use in the circuit,
with an alternating current of 50Hz (or 60Hz), rated operational voltage up to 690V,
in addition to rate operational current up to 620A under the usage category of AC-3/400V;
also this contactor is mainly use for remotely closing and breaking circuits,
and can combine with an appropriate thermal overload relay to form a electromagnetic starter so as to protect the circuits likely to be overloaded in operation; the contactor is well suite for frequently starting and controlling AC motors.
finally Standard: IEC60947-4-1
