Product details

It measures 210 mm high by 145 mm wide by 202 mm deep, with screw fixing to a vertical mounting surface — rotatable ±90° or tiltable ±22.5° front-to-back. The coil connection uses spring-type terminals (2x 0.25–2.5 mm² solid or stranded), while the main power circuit accepts stranded conductors from 70 to 240 mm² through a single 11 mm hole per pole. Rated for continuous duty across -25 to +60 °C ambient during operation, with storage limits from -55 to +80 °C. Mechanical life typical at 10 million operations.

Switching Performance & Duty Ratings

The contactor carries AC-1 (resistive) switching at up to 800 operations per hour, AC-2 (slip-ring motor) at 250 ops/h, AC-3 (squirrel-cage motor starting) at 500 ops/h, and AC-4 (plugging/inching) at 130 ops/h. The AC-3e rating also sits at 500 ops/h. Arcing time falls between 10 and 15 ms. The coil operates on a rated voltage range of 21 to 27.3 V, with a pick-up factor of 0.8 times rated value and a drop-out factor of 1.1 times rated value.

Mounts via screw fixing to a vertical surface.
