Product details

SIRIUS S0 power contactor — 45 mm footprint, screw terminals

The Siemens 3RT1026-1AL20-ZX95 is a SIRIUS S0 power contactor rated for motor switching in AC-2 and AC-4 duty at 400 V, delivering 11 kW in AC-2 and 15.5 A in AC-4. Screw-type terminals on the main circuit accept 2x 0.5–1.5 mm² solid or 2x 0.75–4 mm² stranded, with a max of 2x 10 mm² per clamp.

Motor duty and coordination

At 400 V AC-2 the contactor switches 11 kW motor loads; in AC-4 (frequent reversing or inching) it handles 15.5 A. For Type 2 coordination (no weld) the recommended upstream fuse is gL/gG 35 A; Type 1 coordination allows a 100 A gL/gG fuse. The coil draws 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — verify the control transformer sizing against these inrush figures.

Side-by-side clearance is 6 mm; front protection is IP20, terminal area is IP00.

Frequently asked questions

Where can I buy 3RT1026-1AL20-ZX95 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current pricing and availability confirmation.

What is 3RT1026-1AL20-ZX95's listed depth?

The depth is 91 mm.

What wire sizes does the screw terminal accept?

Solid conductors: 2x 0.5–1.5 mm² and 2x 0.75–2.5 mm², max 2x 0.75–4 mm². Stranded: 2x 1–2.5 mm² and 2x 2.5–6 mm², max 2x 10 mm². AWG equivalents: 2x 16–12 and 2x 14–10, single 8 AWG.

Will 3RT1026-1AL20-ZX95 drop into a panel specified around 3RT1023-1AL20 without rewiring?

Yes — both are S0 frame, 45 mm wide, same DIN rail footprint and screw terminal layout. No rewiring needed for the mounting or terminal positions, but verify the motor load ratings match the 3RT1026's higher capacity.
