Product details

The Siemens 3RT2025-2AU20 is a 3-pole power contactor from the SIRIUS 3RT2 series, size S0. It is rated for AC-3e/AC-3 duty at 17 A and 7.5 kW at 400 V, meaning it is sized for switching three-phase motor loads up to that power — common for small pumps, fans, and conveyors in a control panel.

RoHS compliant since October 1, 2009. REACH Article 33 information is available on the current candidate list.

Size S0 snaps onto a DIN rail. The 1 NO + 1 NC auxiliary contact block is built in, so no separate aux module is needed for basic feedback.
