What It Is and Where It Fits
The Siemens SIRIUS 3RT2325-2CK60 is a size S0 contactor with an AC-operated coil. It's designed for switching motor loads and resistive loads in industrial control panels, and it mounts via screw or snap-on onto standard 35 mm DIN rail per DIN EN 60715. AC coil voltage means it pulls in from an AC control supply — no DC rectifier needed on the coil side. The coil terminals are spring-type, so you're not hunting for a screwdriver on a tight panel layout.
Key Ratings and What They Mean for Your Panel
The auxiliary contact block is rated 10 A at 24 V AC, which covers most PLC output and relay interface circuits you'll find in a standard machine panel. At 230 V AC it's still good for 10 A, so it handles pilot duty loads like indicator lights and small solenoid valves without derating. Operating temperature range of -25 to +60 °C means it's comfortable in an unventilated enclosure near a hot motor starter bank, as long as you keep ambient air moving. Storage range goes from -55 to +80 °C, so it can sit in a cold warehouse or a hot truck without damage.
Mounting and Wiring Notes
Mounting position is flexible — the contactor can be rotated ±180° on a vertical surface and tilted forward or backward ±22.5°. That helps when you're cramming it into a panel with an existing wireway layout. Clearances: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side. Main circuit terminals accept solid wire from 2x 0.5 mm² up to 2.5 mm², or stranded from 1 mm² up to 10 mm². That covers most motor power wiring from fractional-horsepower up to about 7.5 kW at 400 V — typical for a small conveyor or pump starter.
