The Siemens 3RT2017-1UB42-Z W96 is a 3-pole power contactor from the SIRIUS 3RT2 series, size S00. It is rated AC-3e/AC-3 at 12 A and 5.5 kW / 400 V, meaning it is sized for switching three-phase motor loads up to that power — typical for small pumps, fans, or conveyors in a control panel. The coil is 24 V DC and includes an integrated varistor for surge suppression, so no external coil snubber is needed on the DC control circuit. The single NC auxiliary contact (1 NC) is built in, screw-terminal connection.
