The S00 frame keeps the width to 45 mm, height 57.5 mm, and depth 73 mm, allowing dense packing on the DIN rail. Wiring terminals accept solid or stranded conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or 2x 4 mm². This covers typical control wiring from signal-level to moderate power feeds without needing adapters. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. The contactor can be mounted in any orientation, including +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward, which simplifies panel layout.","metaTitle":"Siemens 3RT2518-1AF00 SIRIUS Contactor, Size S00, 45mm","metaDescription":"Siemens 3RT2518-1AF00 SIRIUS contactor, size S00, 45 mm width, screw terminals, 24 VDC coil, 10 A rated current.
