Product details

Rated for motor switching: 10 kW at 500 V and 11 kW at 690 V, with an AC-4 current of 15.5 A at 400 V — that's the high-stress reversing or inching duty where the contactor sees full locked-rotor current on each operation. For AC-2 at 400 V it handles 7.5 kW, covering slip-ring motor starting.

Side-by-side mounting is allowed — no derating gap required for adjacent units at rated load, but watch the 6 mm clearance to grounded metal on the side for arc flash containment.

Main circuit terminals accept solid or stranded wire: 2x (0.25–2.5 mm²) fine-stranded, 2x (1–2.5 mm²) single/stranded, 2x (2.5–6 mm²), or up to 2x 10 mm². AWG equivalents: 2x (16–12), 2x (14–10), 1x 8. For type 2 coordination (no-weld after fault), use gL/gG fuses rated 25 A; for type 1 (welding allowed but safe), 63 A fuses fit. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — all at 50 Hz. Coil data is not in this listing; verify coil voltage from the nameplate before wiring.

Frequently asked questions

What is the depth of 3RT1025-3AD00?

The listed depth is 90 mm, with a width of 45 mm and height of 85 mm.

Will 3RT1025-3AD00 drop into a panel specified for 3RT1023-1AL20?

Both are SIRIUS S0-frame contactors with the same 45 mm width and DIN-rail mounting, so the footprint is identical. The main difference is the coil voltage and auxiliary contact configuration — check the nameplate coil rating before swapping.

What compliance documentation does Siemens provide for 3RT1025-3AD00?

The evidence does not list specific certifications (UL, CSA, CE, RoHS, REACH) for this order code. Typically SIRIUS contactors carry CE marking and are UL/CSA listed; request the manufacturer's declaration from your supplier at quote time.

Where can I buy 3RT1025-3AD00?

It is sourced and quoted to order through independent distribution. Submit an RFQ for current pricing and availability — no stock figures or lead-time numbers are published here.
