Product details

SIRIUS contactor, Size S0, 24 V 50 Hz coil

It carries a 24 V 50 Hz coil and is rated 10 A at 230 V for AC-1 resistive loads, with a maximum switching frequency of 1 000 1/h under AC-1 duty.

The AC-1 rating (10 A at 230 V) governs resistive loads like heaters or lighting; for motor (AC-3) duty, expect a lower figure — the 3RT2526-1AF00 is sized for smaller motor circuits within the S0 frame. The 24 V 50 Hz coil draws 0.25 A at 50 Hz, so a 24 V control transformer must supply that inrush. Auxiliary contacts are built in, saving a separate add-on block for basic feedback.

Accepts 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) stranded per terminal.

Frequently asked questions

Where can I buy 3RT2526-1AF00?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 3RT2526-1AF00's depth?

The depth is 97 mm.

What wire sizes does 3RT2526-1AF00 accept?

It accepts 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) stranded per terminal.

Will 3RT2526-1AF00 drop into a panel specified for 3RT2526-1AD00 without rewiring?

The 3RT2526-1AD00 uses a 24 V DC coil (not 50 Hz AC), so the coil supply differs; the main power terminals and DIN-rail footprint are identical, but the control circuit must match the coil voltage and type — verify before substitution.
