Product details

The front face carries an IP20 rating, while the terminals themselves are IP00 — meaning the wiring compartment is open to the panel environment, so maintain clearance around live parts.

Sizing and fit

At 55 mm wide, 112 mm tall, and 115 mm deep, this Size S2 contactor fits a standard 55 mm-wide DIN-rail slot.

Termination and wiring

The solid range covers two conductors from 0.5 to 1.5 mm², two from 0.75 to 2.5 mm², or a maximum of two from 0.75 to 4 mm². This flexibility covers most motor feeder and control wiring gauges found in panel builds.

Frequently asked questions

What are the key dimensions and mounting for this contactor?

Width is 55 mm, height 112 mm, depth 115 mm. It mounts via screw or snap-on onto a 35 mm standard mounting rail per DIN EN 50022. Side-by-side mounting is supported.

What wire sizes does the main circuit accept?

Solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded: 2x (0.75 to 25 mm²). Terminals are screw-type.
