Eaton 3 Phase DP Motor Starter A27CGF40C040

Magnetic starters are electromagnetically operated switches that provide a safe method for certain motors to be started under a large motor load. The overload relay inside the magnetic starters will prevent the supply voltage from energizing the motor if the starter detects a motor overload situation. It comes complete with Nema 1 Metallic Enclosure and Adjustable Overload Relay from 24 to 40 Amps. This Starter is specifically designed to be used with 20 HP, 3 Phase 440 – 480 Volt Electric Motors. Wiring and Installation Instructions included.
