Product details

It's a 3-pole contactor with spring-type terminals on the coil and an integrated auxiliary switch block (1 NO + 1 NC, 18-8 configuration). Rated for AC-3 motor switching at up to 750 operating cycles per hour (AC-3e also 750 1/h). That's a solid pace for conveyor or pump cycling — not continuous high-speed jogging, but fine for normal start/stop sequences. AC-4 gets 250 1/h for reversing or inching duty; AC-1 resistive loads can run at 1 000 1/h. Coil draws 0.25 A at 50 Hz — a standard 24 VAC control transformer can drive several of these. Wire range accepts 1-10 mm² solid or stranded; auxiliary terminals take 2x 0.5-2.5 mm².

That S0 footprint is the standard for this current class — it fits the same panel cutout as other S0 contactors from the SIRIUS family.

Auxiliary contact ratings cover DC switching: 10 A at 24 V, 2 A at 48 V, 2 A at 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. Also rated 21 A at 480 V — that's useful for pilot-duty loads on 480 V control circuits. AC auxiliary switching times: 4-16 ms operate/release. Arcing time is 10 ms flat.

Frequently asked questions

How do I get current pricing and availability for 3RT2026-2AP00?

3RT2026-2AP00 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 position.

What is 3RT2026-2AP00's listed depth (97 mm) on this component line?

The depth is 97 mm. Combined with a width of 45 mm and height of 102 mm, this is the standard S0 frame size for the SIRIUS contactor family.

What is 3RT2026-2AP00's listed solid (1... 10 mm²) on this component line?

The main contact terminals accept solid wire from 1 to 10 mm², and stranded wire also 1 to 10 mm². Auxiliary contact terminals take 2x 0.5 to 2.5 mm² solid or stranded.

Will 3RT2026-2AP00 drop into a panel that was specified around 3RT2015-2AP02 without rewiring?

Both are S0 frame size on the same 35 mm DIN rail footprint, so the mechanical drop-in and rail spacing are identical. The 3RT2026-2AP00 carries a higher current rating and includes an integrated auxiliary switch block (1 NO + 1 NC) that the 3RT2015-2AP02 may lack depending on its variant — verify the auxiliary contact count against your control schematic before swapping.

What compliance documentation does this brand provide for 3RT2026-2AP00 (RoHS, REACH, UL, IEC)?

As a Siemens SIRIUS product, the 3RT2026-2AP00 is designed to meet IEC/EN 60947-4-1 standards for contactors. For specific RoHS, REACH, and UL documentation, request the manufacturer's declaration with your RFQ — compliance certificates are typically provided on request for current-production parts.
