Product details

Rated for 7.5 kW at AC-2 duty (400 V), this contactor handles slip-ring motor loads — starting and stopping under moderate inrush. The coil is 230 V at 50 Hz, with an operating range of 0.8 to 1.1 times rated voltage — so it pulls in reliably down to about 184 V and holds through line dips. Auxiliary contact ratings cover control voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V — these are the switching limits for pilot devices, PLC inputs, or relay coils in the control circuit.

Screw terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). For stranded, the range is 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents for main contacts: 2x (16 to 12), 2x (14 to 10), 1x 8. Type 1 coordination (contactor may need replacement after fault) uses a 63 A gL/gG fuse.

Frequently asked questions

Will 3RT1025-1AP00-ZW96 drop into a panel specified around 3RT1017-1AP01 without rewiring?

The 3RT1025-1AP00-ZW96 is a larger S0 frame contactor compared to the 3RT1017-1AP01 (which is typically S00). The physical footprint differs — the S0 is 45 mm wide versus S00 at 45 mm as well, but the depth and terminal layout may require re-drilling the mounting plate. The screw terminal wiring scheme is similar, but verify the terminal spacing and auxiliary contact arrangement against your existing panel layout before assuming a drop-in fit.

What compliance documentation is available for this part?

As a Siemens SIRUS product, the 3RT1025-1AP00-ZW96 carries CE marking for the European market and is designed to IEC/EN 60947-4-1 standards. RoHS and REACH declarations are standard from Siemens for current-production parts. Specific UL/CSA file numbers are not listed in this evidence; request the manufacturer's declaration for your jurisdiction.

What are the key motor ratings for this contactor?

At AC-2 duty (400 V), it is rated for 7.5 kW. At AC-4 duty (400 V), the current rating is 15.5 A. At 500 V, the power rating is 10 kW; at 690 V, it is 11 kW. The AC-12 maximum operating current is 10 A.
