Product details

Rated for 36 A at both 480 V and 600 V, it covers common North American motor voltages up to 30 hp at 460/480 V. The 20...690 V rated voltage range and 125 A at 400 V (presumably for resistive loads, as the AC-3 motor rating is lower) give flexibility across global supply systems.

Dimensions are 55 mm wide, 140 mm high, 149 mm deep, so it occupies one standard modular width on the rail. Mounting position is any, and clearance requirements are 50 mm upwards, 50 mm downwards, 10 mm to the side — zero forwards or backwards — which simplifies enclosure sizing. Main circuit connections use screw-type terminals accepting 2x 1...25 mm² or 1x 1...35 mm² solid or stranded; main contact screws are M6.

Environmental and operating limits

Maximum switching frequency at AC-3 (motor) duty is 15 operations per hour, which matches typical motor-starting cycles on conveyors or pumps.
