Siemens 3RT2026-1AF00 Soft Starter

Siemens 3RT2026-1AF00 is a 3-pole power contactor from the Sirius 3RT2 family, designed for AC-3e/AC-3 duty and rated to carry 25 A while switching up to 11 kW at 400 V, with a 110 V AC (50 Hz) control coil. It provides one normally open and one normally closed auxiliary contact for interlocking and control feedback, uses screw terminals for secure wiring, and is designated as size S0 within the 3RT2 lineup. The coil consumes 9.8 W, reflecting a compact 110 V AC coil, and the 3-pole, 11 kW/400 V rating makes it well suited for motor-control applications such as starting and stopping loads in automation panels that require AC-3 duty and a 1NO+1NC auxiliary arrangement.
