Product details

The Siemens 3RT2026-1AM20 is a SIRIUS S0 power contactor — the core switching element in a motor starter or load-management circuit. Screw-type terminals on the coil and main contacts, with an integrated auxiliary switch. Rated for 750 switching cycles per hour at AC-3 duty (motor starting) and the same at AC-2. At AC-1 (resistive loads) it handles 1,000 ops/h; at AC-4 (plugging/inching) the rate drops to 250 ops/h. The auxiliary contact block carries 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. At 230 V it is rated for 3 hp motor load.

The S0 frame size is the standard footprint for contactors in this current class — it occupies one DIN-rail module width (45 mm). Two conductors can share a terminal: 2x 0.5–1.5 mm² or 2x 0.75–2.5 mm². Main contacts accept 16 to 8 AWG.

Coil sealing current: 0.25 A at 50 Hz, 0.28 A at 60 Hz. Operating time at AC: 4 to 16 ms. Arcing time: 10 ms.

Frequently asked questions

Where can I buy 3RT2026-1AM20?

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

What is the closest functional equivalent to 3RT2026-1AM20?

The 3RT2016-1AG62 is a sibling in the same SIRIUS S0 family. The main difference is the coil voltage and terminal type — verify your control voltage and wiring preference before substituting. Both share the same S0 footprint and similar switching ratings.

What is the depth of 3RT2026-1AM20?

The depth is 97 mm. Combined with the 45 mm width and 85 mm height, it fits the standard S0 contactor footprint.

What wire sizes does 3RT2026-1AM20 accept?

Solid or stranded conductors from 1 to 10 mm². Two conductors can share a terminal: 2x 0.5–1.5 mm² or 2x 0.75–2.5 mm². Main contacts accept 16 to 8 AWG.

Will 3RT2026-1AM20 drop into a panel specified for 3RT2016-1AG62?

Both are S0 frame size with the same 45 mm width and 85 mm height, so the mechanical footprint is identical. However, verify the coil voltage and terminal type — the 3RT2026-1AM20 uses screw-type terminals, while the 3RT2016-1AG62 may differ. No rewiring of the panel layout is needed if the coil voltage matches.
