The Siemens 3RT2326-2AP00 is a SIRIUS Size S0 contactor rated for main contact currents of 18 to 8 A, with an AC coil. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the coil connection uses spring-type terminals for fast wiring.
Mounting and integration
The mounting position allows +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward/backward — useful when panel layout forces an angle. Clearance: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side.
Ratings and what they mean
Main contact rating of 18 to 8 A covers typical motor and resistive loads in a Size S0 frame — the lower end (8 A) is the continuous thermal current for the contactor's rated duty. The AC coil draws 0.25 A at 50 Hz (230 V rated value), so the control transformer or PLC output must supply that inrush without voltage sag. Arcing time is 10 to 10 ms, consistent across the switching range.
