Rated for 11 kW at 690 V AC-3, it handles motor loads up to that power class, with a mechanical life of 10 million operations. At 400 V AC-3, it's rated 7.5 kW, and in AC-4 duty (plugging, inching) it carries 15.5 A at 400 V — so it's not just a run-of-the-mill starter; it's built for some reversing or jogging cycles. The auxiliary contact ratings are listed across several control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V — that covers most PLC or relay interface voltages you'll see in a panel. The maximum operating altitude of 2 000 m covers most sites short of high-mountain installations. Screw terminals accept 2x (0.25...2.5 mm²) solid or stranded, with a top range of 2x 10 mm² — enough for the main motor leads on a 11 kW circuit.","metaTitle":"Siemens SIRIUS 3RT1025-3AF00 Power Contactor, 3-Pole, 11 kW","metaDescription":"Siemens 3RT1025-3AF00 SIRIUS power contactor, 3 NO main contacts, 11 kW at 690 V AC-3.
