Siemens SIRIUS 3RT2325-1AP00 — Size S0 Contactor, 24 V AC Coil
The Siemens SIRIUS 3RT2325-1AP00 is a Size S0 contactor with a 24 V AC, 50 Hz coil rated at 230 V. It mounts via screw or snap-on onto 35 mm DIN rail per EN 60715, with a +/-180° rotation and +/-22.5° tilt allowance on vertical surfaces. The screw-type magnet coil termination and auxiliary switch are integrated, with one instantaneous contact.
The arcing time of 10–10 ms is consistent for AC switching — expect clean break on resistive and light inductive loads. The 10 mm clearance upwards, downwards, and forwards plus 6 mm sideways is the minimum air gap for heat dissipation and arc flash — don't crowd it against busbars or other contactors.
The 3RT2325-1AP00 accepts solid conductors up to 2x (0.5–1.5 mm²) and 2x (0.75–2.5 mm²), and stranded up to 1–10 mm². The 60 mm width and 85 mm height fit standard S0 footprint on DIN rail. Depth is 97 mm — check your enclosure depth if you're mounting a row of these with wiring ducts.
