Product details

What you're looking at

The Siemens 3RT1026-3AG20-ZX95 is a SIRIUS S0 power contactor — the frame size tells you the physical envelope and the maximum motor current it can handle. It's rated for 10 A at 24 V for the coil, and AC-4 duty at 15.5 A at 400 V, which is the heavy reversing/plugging load that kills smaller contactors fast.

That's the duty cycle that wears contacts fastest. The coil pulls 10 A at 24 V, so size your control transformer and fuse accordingly. The S0 frame is 45 mm wide and 85 mm tall, with a 90 mm depth — fits standard DIN-rail enclosures.

Coordination and wiring

Main circuit wiring accepts screw terminals: 2x (0.25 to 2.5 mm²) solid or 2x (1 to 2.5 mm²) stranded, up to 2x 10 mm².

Frequently asked questions

Where can I buy 3RT1026-3AG20-ZX95?

It's sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the AC-4 rating and why does it matter?

The AC-4 rating is 15.5 A at 400 V. That's the maximum current the contactor can handle during frequent starts, stops, or reversing — the harshest duty for a contactor. If your motor load exceeds this, step up to a larger frame.

Will 3RT1026-3AG20-ZX95 drop into a panel specified around 3RT1023-1AL20?

Both are SIRIUS S0 contactors on a 35 mm DIN rail, so the mechanical footprint is the same. The 3RT1026 has a higher AC-4 current rating (15.5 A vs the 3RT1023's lower rating), so it's a direct replacement if the wiring and fuse coordination are adjusted accordingly.
