NC7 AC Contactor


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