Siemens SIRIUS 3RT2327-1AF00 — S0 Contactor, AC Coil, 1 N/O
The S0 frame size gives it a compact footprint of 85 mm height, 60 mm width, and 97 mm depth — a standard panel-building dimension that fits alongside other S0 accessories on the same DIN rail.
Wiring and Clearance
Main circuit terminals accept 1 x 10 mm² stranded or 2 x (0.5 to 1.5 mm²) solid, with the auxiliary/coil terminals taking 2 x (0.5 to 1.5 mm²) solid or 2 x (0.75 to 2.5 mm²) stranded. That covers most control-circuit wire gauges in a standard panel. Minimum clearance around the contactor: 10 mm upwards, 10 mm downwards, 10 mm forwards, and 6 mm at the side. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, which helps when fitting into tight or angled enclosures.
Ratings and Switching Capability
The single N/O main contact is rated for AC switching with an arcing time of 10 to 10 ms. The contactor carries auxiliary switch capability, and the typical mechanical life is 10,000,000 operations — a figure that reflects the S0 frame's durability in high-cycle applications like conveyor or pump control. The AC coil is rated at 110 V at 50 Hz. The contactor's operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C.
