Product details

It is rated for 11 kW at 500 V in AC-3 duty, which covers the majority of standard induction motor starting applications at that voltage level. The coil is wound for 92 V at 50 Hz and 110 V at 60 Hz, with an operating range of 0.8 to 1.1 times the rated voltage, meaning it pulls in reliably even if the control supply sags to about 74 V.

The S0 frame occupies 45 mm width, 85 mm height, and 91 mm depth — a compact footprint that fits standard 600 mm deep enclosures with room for wiring gutters. The main circuit uses screw-type terminals accepting 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a maximum of 2x 4 mm². For the main contacts, the range extends to 2x 10 mm² or 1x AWG 8. Pollution degree 3 rating means it's suitable for the conductive-dust environment typical of a control panel without conformal coating.

The single normally-open auxiliary contact is rated for 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. These are the make-and-break capacities for the control circuit; if you're switching a PLC input or a relay coil, stay within these limits to avoid contact welding. The ratings drop with voltage because the arc energy increases, so at 220 V DC the contact is limited to 0.3 A.

Frequently asked questions

What are the key motor power ratings for this contactor?

It is rated for 11 kW at 500 V in AC-3 duty, 11 kW at 400 V in AC-2 duty, and carries a continuous current of 15.5 A at 400 V in AC-4 duty for plugging and inching applications.

What coil voltage does this contactor use?

The coil is rated for 92 V at 50 Hz and 110 V at 60 Hz, with an operating range of 0.8 to 1.1 times the rated voltage.

What are the mounting dimensions and rail type?

It mounts on 35 mm DIN rail per EN 50022, with a width of 45 mm, height of 85 mm, and depth of 91 mm. Side-by-side mounting is permitted with zero lateral spacing.

What wire sizes does the main circuit accept?

The screw terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, with a maximum of 2x 4 mm². For the main contacts, the range extends to 2x 10 mm² or 1x AWG 8.
