Product details

What this SIRIUS S0 contactor carries

The Siemens SIRIUS 3RT1026-3AG60 is a size S0 power contactor rated for motor switching at 11 kW in AC-2 duty at 400 V — that's the standard rating for slip-ring motor starting and reversing, where the contactor makes and breaks the load under normal running conditions. Screw-type terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. AWG equivalents: 2x (16 to 12) or 1x 8.

This lets the panel designer choose between tighter protection or higher fault tolerance depending on the application.

Integration notes

This lets you pack multiple S0 contactors on a single DIN rail without derating for proximity. Coil operating range is 0.8 to 1.1 x rated voltage at 50 Hz, and 0.85 to 1.1 at 60 Hz. The coil is rated for 100 V at 50 Hz and 100 to 110 V at 60 Hz — confirm your control voltage matches the 50 Hz or 60 Hz column before wiring.

Frequently asked questions

What are the key motor ratings for this contactor?

AC-2 duty at 400 V: 11 kW. AC-4 duty at 400 V: 15.5 A. AC-12 resistive load: 10 A maximum. For DC switching, it's rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V.

What fuse coordination is required?

Type 2 coordination requires a gL/gG 35 A fuse upstream. Type 1 coordination allows a gL/gG 100 A fuse. The choice depends on whether the contactor must survive a short-circuit fault without damage (Type 2) or can be replaced afterward (Type 1).

Will this fit a panel designed for 3RT1034-1AN60-1AA0?

Both are SIRIUS S0 frame contactors with the same 45 mm width and DIN rail mounting, so the mechanical footprint is identical. The difference is in the ratings — the 3RT1034 variant is a higher-current version. Verify your load current against the 3RT1026's AC-2/AC-4 ratings before substituting.
