This AC contactor is suitable for using in circuits up to rated voltage
of 660V AC 50Hz or 60Hz, rated current up to 95A, for making, breaking,
frequently starting and controlling the AC motor. Combined with the
auxiliary contact block, timer delay and machine-interlocking devices,
it becomes the delay contactor, mechanical interlocking contactor, or
star-delta starter. With the thermal relay, it is combined into the
electromagnetic starter. The contactor is produced according
to IEC, VDE, and BS standards.
