Product details

SIRIUS 3RT1026-1AB00 — Power Contactor, S0, 24 V 50 Hz Coil

The front face is rated IP20 (finger-safe), while the terminal area is IP00 — expect exposed live parts at the wiring point. Rated operational current at AC-12 is 10 A; for motor loads, the AC-2 rating at 400 V is 11 kW, and AC-4 at 400 V is 15.5 A. Coil draws 0.8 to 1.1 A at 50 Hz.

Main and auxiliary circuits use screw-type terminals. Main contacts accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid; auxiliary contacts accept 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) solid/stranded, max 2x 10 mm². AWG equivalents: main 2x (16 to 12), 2x (14 to 10), 1x 8; auxiliary 2x (20 to 16), 2x (18 to 14), 1x 12. Side-by-side mounting is permitted — no derating gap required.

Frequently asked questions

How do I get current pricing and availability for 3RT1026-1AB00?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is 3RT1026-1AB00's depth?

The depth is 91 mm, with a width of 45 mm and height of 85 mm.

What wire sizes does 3RT1026-1AB00 accept on the main terminals?

Main terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid; AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8.

Will 3RT1026-1AB00 drop into a panel specified for 3RT1017-1AD02?

Both are S0 frame contactors on 35 mm DIN rail, so the mounting footprint and rail clip are identical. The 3RT1026-1AB00 uses a 24 V 50 Hz coil; verify the control voltage matches your panel's supply before swapping.
