The Siemens 3RT2325-1BE40 is a 4-pole contactor from the SIRIUS family, rated 35 A in AC-1 duty at 400 V and 40 °C ambient — that is the resistive-load rating, so it handles heater banks, lighting, and transformer primary switching where inrush is modest. The 60 V DC coil means it is built for a DC control bus, common in industrial panels running 48 V or 60 V DC supplies. The size S0 frame keeps the DIN-rail footprint compact for panel density. The auxiliary contact block is built in: 1 normally open and 1 normally closed, enough for basic feedback or interlock without an add-on module. Screw terminals suit panel shops that prefer traditional wiring over spring-cage.
The 95 x 65 x 115 mm package leaves room alongside a motor-protective circuit breaker in the same rail segment. The 60 V DC coil draws about 2.5 A inrush then holds at roughly 0.25 A — check your DC supply headroom if you are ganging multiple contactors on one power supply. Wire the coil suppression diode across the DC terminals; the coil is polarity-sensitive.
