SIRIUS 3RT2327-2AP00 Contactor — S0 Frame, 230 V AC Coil
The Siemens SIRIUS 3RT2327-2AP00 is a Size S0 contactor with a 230 V AC 50 Hz coil and spring-type terminals. It switches main contacts rated for motor loads up to 10 A at 24 V and 10 A at 230 V, with a mechanical life of 10 million operations. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and accepts one auxiliary switch block.
What the Ratings Mean for Fit
The 10 A rating at 24 V and 230 V covers small motor, resistive, and general-purpose loads in control panels. The 10 million mechanical cycles mean this contactor is suited for high-cycling applications like conveyor indexing or packaging lines where the contactor cycles frequently. The spring-type terminals accept solid wire 2x (0.5...2.5 mm²) or stranded 1...10 mm² — no ferrules required for solid, but stranded conductors benefit from ferrules to prevent whiskering under the spring cage.
Integration & Mounting
The 60 mm wide, 102 mm tall, 97 mm deep S0 frame fits standard DIN-rail enclosures. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. Clearance requirements: 10 mm upwards, 10 mm downwards, 10 mm forwards, 6 mm at the side. Operating temperature range -25 to +60 °C; storage -55 to +80 °C. The contactor accepts up to two auxiliary switch blocks.
