Siemens 3RT2025-1AP00 SIRIUS Power Contactor 17A 3P 230V AC

The Siemens 3RT2025-1AP00 is a 3-pole SIRIUS power contactor from the 3RT2 series, rated 17 A and 7.5 kW at 400 V in AC-3/AC-3e duty. It is equipped with a 230 V AC, 50 Hz control coil and includes built-in auxiliary contacts (1 NO + 1 NC). Screw terminals and size S0 make it a direct-fit for standard industrial motor control panels operating up to 690 V.
