Product details

What this contactor delivers in the panel

The Siemens 3RT1026-1AN00 is a SIRIUS power contactor in size S0, built for switching three-phase motor loads up to 11 kW at 500 V or 690 V. For AC-2 duty (slip-ring motors) it carries the same 11 kW at 400 V. The S0 frame keeps the footprint compact for a 11 kW class contactor.

Accepts solid or stranded conductors: 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max 2x (0.75…4 mm²) for the control circuit; for the main circuit, 2x (1…2.5 mm²), 2x (2.5…6 mm²), max 2x 10 mm², or AWG equivalents 2x (16…12), 2x (14…10), 1x 8. Rated for pollution degree 3, so suitable for industrial control panels without additional enclosure sealing.

Frequently asked questions

How do I get pricing and availability for 3RT1026-1AN00?

Submit an RFQ through this listing. The part is sourced and quoted to order; current pricing and availability are confirmed at quote time.

What is the depth of 3RT1026-1AN00?

The depth is 91 mm.

What conductor sizes does the control circuit accept?

The control circuit accepts 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max 2x (0.75…4 mm²) solid or stranded.

Will 3RT1026-1AN00 drop into a panel specified for 3RT1023-1AL20 without rewiring?

Both are SIRIUS S0 contactors with the same DIN-rail footprint and screw-terminal main circuit, so the mechanical fit and wiring scheme are identical. The difference is in the coil voltage and switching ratings — verify the coil voltage matches your control circuit before swapping.
