Product details

Motor-Rated Contactor for 400 V Three-Phase Lines

The Siemens 3RT2526-1AV00 is a SIRIUS 3RT25 power contactor rated for AC-3 duty at 25 A, switching 11 kW motor loads on a 400 V three-phase supply. The 4-pole configuration provides 2 normally-open and 2 normally-closed main contacts, with an additional 1 NO + 1 NC auxiliary contact block integrated on the front. Coil is 400 V AC, 50 Hz, matching standard European industrial mains without a control transformer.

Sizing and Panel Fit

Screw terminals accept up to 6 mm² conductors for the power circuit. The auxiliary contact set (1 NO + 1 NC) is factory-fitted, eliminating a separate add-on block for basic feedback or interlocking.
