The Siemens 3RT2325-1AP60 is a SIRIUS 3RT23 contactor designed for reliable switching of electrical loads in industrial control panels and automation systems. This 4-pole contactor features four normally open main contacts and an integrated auxiliary contact arrangement of 1 NO + 1 NC, making it suitable for control, signalling and interlocking functions within motor and load switching applications.
Rated for AC-1 operation at 35 A at 400 V and 40 °C, the 3RT2325-1AP60 provides dependable performance for resistive and lightly inductive loads. It also supports AC-3 and AC-4 operation at 15.5 A at 400 V, with an operating power rating of 7.5 kW. The contactor uses an AC coil with a control supply voltage of 220 V at 50 Hz or 240 V at 60 Hz.
Built in Siemens size S0 format, this contactor is compact enough for space-conscious panel layouts while maintaining robust electrical and mechanical capability. It has screw-type terminals for the main, auxiliary and control circuits, allowing secure wiring with common industrial conductor sizes. The unit can be mounted by screw fixing or snapped onto a 35 mm standard mounting rail, supporting straightforward integration into existing control assemblies.
The 3RT2325-1AP60 is designed with IP20 front protection and finger-safe touch protection from the front, helping support practical use in enclosed electrical installations. With a typical mechanical service life of 10 million switching cycles, a 690 V rated operating voltage, and a 6 kV surge voltage rating for both main and auxiliary circuits, it is a durable contactor for demanding industrial environments.
