Product details

Panel Fit and Mounting Reality

Envelope is 130 mm deep by 55 mm wide by 114 mm tall, so it fills a standard 55 mm-wide slot on the rail. Clearance around it: 10 mm up, down, and forward; 6 mm at the sides — tight enough that a crowded rail needs the side gap respected. That covers most panel layouts without a special bracket.

Motor Switching Duty and Coil

Rated 65 A at 480 V in AC-3 duty — that's the motor-switching current that matters for sizing. It handles 500 operations per hour max in AC-3, 150 in AC-4 (plugging / inching). The AC-1 resistive rating is 700 ops/h. Coil is 110 V at 50 Hz, draws 0.36 A inrush at 50 Hz (0.39 A at 60 Hz). The magnet coil terminates on spring-type terminals — no screwdriver needed for the coil wires, which speeds up panel wiring. Auxiliary switch is built in — main contacts have 18…1 configuration.
