Product details

S6 frame contactor for motor and resistive loads

The 3RT1456-6AB38-0PA5: The 24 V AC/DC coil with screw-type terminals keeps the control wiring straightforward — no special DC suppression needed on the coil circuit since the magnet accepts both supply types.

Physical fit and mounting flexibility

At 172 mm high, 170 mm deep, and 120 mm wide, this contactor occupies a standard S6 footprint on the panel backplate. Fastening is by screw fixing through a single 9 mm hole — no DIN-rail adapter on this variant, so budget for drilled and tapped mounting points in the enclosure layout.

Wiring capacity and auxiliary contact ratings

Main power wiring accepts stranded conductors from 25 mm² up to 120 mm² — sized for the full S6 current rating.
