LC1-D Series AC Contactor

Description

LC1-D Series AC Contactor is used in AC 50Hz or 60Hz circuits up to 660V, with rated current up to 620A, for making, breaking, frequent starting and control of AC motors.

Applications

The contactor can be combined with auxiliary contact blocks, timer-delay units and mechanical interlocking devices to form delay contactors, mechanical interlocking contactors and star-delta starters. When combined with a thermal relay, it forms an electromagnetic starter.

The product conforms to IEC60947-4-1.
