Application
The OMC-D series AC Contactor is specifically designed for use in circuits with a rated voltage up to 660V AC at 50Hz or 60Hz, and a rated current up to 95A. This contactor is ideal for making, breaking, and frequently starting or controlling AC motors. It can be combined with auxiliary contact blocks, delay timers, and machine-interlocking devices to become a delay contactor, mechanical interlocking contactor, or star-delta starter. When paired with a thermal relay, it transforms into an electromagnetic starter. The OMC-D series complies with IEC60947-4, ensuring high reliability and performance.
