HC-D series AC contactors is suitable for using in the circuits up to the ratedvoltage 660V AC 50Hz or 60Hz, rated current up to 95A, for making, breaking,frequently starting & controlling the AC motor. Combined with the auxiliarycontact block, timer delay & machine-interlocking device etc, it becomes the delaycontactor, mechanical interlocking contactor, star-delta starter. With the thermalrelay, it is combined into the electromagnetic starter. The contactor is producedaccording to IEC947-2, VDE0660 & BS5452.
