Product details

SIRIUS S0 power contactor — panel integration brief

The Siemens 3RT1026-3AG16 is a SIRIUS S0-frame power contactor rated for motor switching at 11 kW on 400 V AC-2 duty and 15.5 A on AC-4 (reversing/inching).

Motor duty and coordination

AC-2 at 400 V delivers 11 kW, which covers wound-rotor motor loads where starting current stays moderate. Both are standard fuse classes available from any electrical wholesaler.

The S0 frame size keeps the footprint compact at 65 mm wide × 85 mm tall × 91 mm deep.

Main current circuit uses screw-type terminals accepting 2x (0.25–2.5 mm²) solid, 2x (1–2.5 mm²) or 2x (2.5–6 mm²) stranded, and up to 2x 10 mm². AWG equivalents are 2x (16–12) solid, 2x (14–10) stranded, and 1x 8. Auxiliary contacts: 2 instantaneous, rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC. The auxiliary contact ratings cover typical PLC-level signal switching and control relay loads.

Frequently asked questions

What is the closest functional second-source for 3RT1026-3AG16?

The 3RT1023-1AL20 is a smaller S0-frame contactor (lower current rating) but shares the same mounting footprint and terminal layout. It will drop into the same DIN-rail panel without rewiring, but verify your motor current against its lower AC-3/AC-4 ratings before substituting.

What compliance documentation does Siemens provide for 3RT1026-3AG16?

Siemens SIRIUS contactors carry CE marking per Low Voltage Directive 2014/35/EU and are designed to meet IEC 60947-4-1. RoHS and REACH declarations are available from Siemens Industry Online Support. UL/CSA listings are standard on the 3RT1 series but should be confirmed against the specific variant code.

Where can I buy 3RT1026-3AG16 and what is the lead time?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm lead time and price.
