Product details

At AC-3 duty (motor switching) it is rated for up to 1000 operating cycles per hour, and at AC-4 (inching/jogging) the maximum drops to 300 cycles per hour — the mechanical life is 10 million typical operations, so it holds up in high-cycle applications.

Clearance and wiring — what fits in the panel

The main contact terminals accept 1 to 10 mm² solid or stranded, and the auxiliary wiring can take 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. The arcing time sits between 10 and 10 ms, and the operating temperature range is -25 to +40 °C; storage range is -55 to +80 °C.

Frequently asked questions

How do I get pricing and availability for 3RT2025-1AB00-1HA1?

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

What is the closest functional second-source to 3RT2025-1AB00-1HA1?

The 3RT2036-1AC20-ZX95 is a peer in the same SIRIUS contactor family, but it is a different size frame and carries different ratings. The 3RT2025-1AB00-1HA1 is a size S0 contactor; the 3RT2036-1AC20-ZX95 is a larger frame. Panel fit and wiring will differ — verify the footprint and terminal ratings before substituting.

What is the depth of 3RT2025-1AB00-1HA1?

The depth is 97 mm.

What solid wire size does 3RT2025-1AB00-1HA1 accept?

The main contact terminals accept solid wire from 1 to 10 mm².

Will 3RT2025-1AB00-1HA1 drop into a panel specified for 3RT2036-1AC20-ZX95?

No — the 3RT2025-1AB00-1HA1 is a size S0 contactor, while the 3RT2036-1AC20-ZX95 is a larger frame. The footprint, DIN rail spacing, and terminal layout differ. Panel rewiring and possibly enclosure modifications would be needed.
