Product details

The 45 mm width leaves room for adjacent devices in a crowded enclosure. Rated 11 kW at AC-2 400 V and 15.5 A at AC-4 400 V, this contactor handles the inductive load of a motor start-run cycle. AC-2 covers slip-ring motors; AC-4 covers plugging and inching. The 10 A continuous rating at AC-12 (resistive) gives a headroom check for non-motor loads.

Terminals and wiring

Main circuit terminals are screw-type, accepting 2x (1...2.5 mm²) or 2x (2.5...6 mm²) solid/stranded, with a max of 2x 10 mm². Control circuit terminals take 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²). AWG equivalents: main contacts 2x (16...12), 2x (14...10), 1x 8. Strip length and torque follow standard Siemens S0 practice — no special tooling needed. Side-by-side mounting is allowed without derating at 6 mm spacing. Front face carries IP20; the terminal area is IP00 — keep live parts behind a panel door or cover.

Frequently asked questions

What is the closest functional second-source for 3RT1026-1AG20-ZW98?

The 3RT1023-1AL20 is a smaller S0 variant with lower motor ratings; it shares the same DIN footprint and screw terminals but will not match the 11 kW AC-2 rating. For a direct swap at the same power, stick with the 3RT1026-1AG20-ZW98.

Will 3RT1026-1AG20-ZW98 drop into a panel specified around 3RT1023-1AL20?

Yes — both are S0 size, 45 mm wide, snap onto 35 mm DIN rail, and use screw terminals. No rewiring needed if the existing wire gauges fall within the 3RT1026's terminal range.

Where can I buy 3RT1026-1AG20-ZW98?
