What It Is and Where It Fits
The Siemens SIRIUS 3RT2326-2AB00 is a Size S0 contactor with a 24 VAC 50 Hz coil, spring-type terminals, and a 10 A rated operational current at 24 V. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting into standard control panels and motor starter assemblies.
Key Ratings and What They Mean for Fit
The 24 VAC 50 Hz coil pull-in is rated for 10 A at 24 V, meaning it can switch resistive loads up to that current at the coil voltage. The S0 frame size (102 mm height, 60 mm width, 97 mm depth) determines panel layout — it occupies a standard contactor footprint with 10 mm clearance upwards, downwards, and forwards, and 6 mm at the sides for heat dissipation and arc containment. Operating temperature range of -25 to +60 °C covers most indoor industrial environments; storage range of -55 to +80 °C allows for unheated warehouses. The spring-type coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire, matching typical control wiring practices.
Panel Integration Notes
Snap-on mounting onto 35 mm DIN rail per DIN EN 60715, with +/-180° rotation possible on a vertical mounting surface and +/-22.5° tilt forward/backward. The spring-type terminals on the coil reduce wiring time compared to screw terminals — strip to 8 mm, insert, done. Main contact terminals accept 1 to 10 mm² stranded wire. An auxiliary switch is attachable (2 maximum), allowing feedback to a PLC or status indication without a separate block.
