Product details

Rated for 11 kW at 400 V in AC-2 duty (slip-ring motor starting) and 15.5 A at 400 V in AC-4 duty (plugging/inching), this contactor handles the high inrush and frequent switching cycles of demanding motor applications. The main circuit connects via screw-type terminals accepting 2x (0.25...2.5 mm²) solid or 2x (1...2.5 mm²) stranded, up to 2x 10 mm² maximum — sized for the S0 frame's current range.

Key ratings in context

At 500 V and 690 V, the contactor is rated for 11 kW in AC-3 duty (squirrel-cage motor starting), which covers the bulk of standard induction motor switching on 400/480 V and 690 V networks. Type 1 coordination allows a 100 A fuse. This tells the panel builder what upstream protection keeps the contactor repairable after a fault.

Side-by-side mounting is permitted with zero clearance, so multiple contactors can pack tightly on the rail.

Frequently asked questions

What is the closest functional alternative if I cannot source this exact order code?

The 3RT1034-1AN60-1AA0 is a higher-current SIRIUS contactor in a larger frame; it will not drop into the same panel footprint without re-drilling the mounting rail or widening the enclosure cutout. For the same S0 frame size and similar ratings, the 3RT1017-1AP01 is the closest peer, but verify the coil voltage and auxiliary configuration against your BOM before substituting.

What is the depth of this contactor?

The depth is 90 mm from the mounting surface to the front of the terminal cover.

What wire sizes does the main circuit accept?

The screw-type terminals accept 2x (0.25...2.5 mm²) solid or 2x (1...2.5 mm²) stranded conductors, with a maximum of 2x 10 mm².
