Product details

SIRIUS 3RT2025-1AF00 — Power Contactor, Size S0, 24 VDC Coil

The coil is 24 VDC with screw-type terminals, rated for 10 A at 24 V rated value and 14 A at 480 V rated value. Switching frequency varies by duty class: up to 1 000 operations per hour at AC-1, AC-2, AC-3, and AC-3e maximum, and 300 operations per hour at AC-4 maximum. This means the contactor handles high-cycle motor starting (AC-3) at full rated current without derating, while the lower AC-4 rate accounts for the heavier wear of inching and plugging duty.

Main contact terminals accept solid or stranded wire from 1 to 10 mm²; auxiliary contact terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). Wire preparation is straightforward with screw terminals — no special ferruling required for stranded up to 10 mm². Dimensions: Width 45 mm, Height 85 mm, Depth 97 mm.

Frequently asked questions

What is the closest functional second-source for 3RT2025-1AF00?

The 3RT2036-1AC20-ZX95 is a peer SIRIUS contactor but with a 24 VAC coil and a different auxiliary configuration. It will not drop into the same panel without rewiring because the coil voltage and terminal assignments differ. For a direct drop-in replacement, stick with the 24 VDC coil variant like 3RT2526-1AF00 or 3RT2526-1AD00 — but confirm auxiliary contact count matches your circuit.

Where can I buy 3RT2025-1AF00 and get current pricing?

This part 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 price and lead time.

What is the depth of 3RT2025-1AF00?

The depth is 97 mm. Combined with a width of 45 mm and height of 85 mm, it fits in a standard S0 DIN-rail footprint.

What wire sizes does 3RT2025-1AF00 accept?

Main contacts accept solid or stranded wire from 1 to 10 mm². Auxiliary contacts accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). All terminals are screw-type.
