The Siemens 3RU1116-1FC1 is a SIRIUS thermal overload relay in size S00, designed to protect motors against overload and phase failure by tripping according to CLASS 10 characteristics. The cage clamp terminals on the main current circuit accept solid conductors 2x (0.5... 2.5 mm²) or finely stranded with core end processing 2x (0.5... 1.5 mm²), simplifying wiring in DIN-rail enclosures.
The S00 frame size (45 mm wide, 92 mm high, 78 mm deep) fits the compact footprint of Siemens SIRIUS contactor assemblies, allowing direct mounting without additional adapters.
Integration notes
Mounts on a vertical surface with ±135° rotation and ±45° tilt to front/back, giving flexibility in panel layout while maintaining clearance: 0 mm upwards, forwards, and backwards; 6 mm at the side. Operates from -20 to +70 °C and stores from -55 to +80 °C, covering most indoor industrial environments without derating. Shock rated at 8g / 10 ms, suitable for mounting on machinery subject to vibration from conveyors or compressors.
