Product details

At 45 mm wide and 90 mm deep, it fits a standard panel slot for this frame size.

Rated for AC-2 duty at 400 V at 7.5 kW and AC-4 at 400 V at 15.5 A — the AC-2 figure governs motor starting with moderate overload, while AC-4 covers plugging and inching where the contactor makes and breaks stalled-rotor current. For resistive loads (AC-12), it handles 10 A. The 50 Hz coil operates across 0.8 to 1.1 times rated voltage, so a 400 V coil holds in at 320 V and picks up reliably at 440 V. The front face carries IP20 protection; the terminals themselves are rated IP00, so the contactor needs enclosure protection against accidental contact.

Termination and wiring

Main circuit terminals accept solid or stranded conductors: 2x (0.25 to 2.5 mm²) and 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²), with a maximum of 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), or 1x 8.

Frequently asked questions

Where can I buy 3RT1025-3AV00 and how do I get a price?

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 3RT1025-3AV00's listed depth?

The depth is 90 mm, which fits standard S0-size contactor panel layouts.

What wire sizes does the 3RT1025-3AV00 accept?

Main terminals accept 2x (0.25 to 2.5 mm²) solid, plus 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) stranded, max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), or 1x 8.

Will 3RT1025-3AV00 drop into a panel specified for 3RT1023-1AL20?

Both are SIRIUS S0-size contactors with the same 45 mm width and DIN rail mounting, so the mechanical footprint is identical. The 3RT1025-3AV00 carries 3 NO main contacts versus the 3RT1023-1AL20's different contact configuration — verify the auxiliary contact count and coil voltage before swapping.
