Mounts directly onto a contactor — no DIN rail required. The 45 mm width and 87 mm height fit the S00 footprint, with zero clearance needed upwards, forwards, backwards, or downwards. Side clearance of 6 mm is sufficient. The mounting position allows ±135° rotation and ±45° tilt front/back from vertical, giving panel builders flexibility in tight enclosures. Accepts solid conductors 2x (0.5…1.5 mm²) and 2x (0.75…2.5 mm²), or finely stranded with ferrule. AWG equivalents: 2x (20…16), 2x (18…14), 2x 12. The 78 mm depth leaves enough finger space behind the panel for wiring access. ## Environmental and electrical ratings Withstands 8g / 10 ms shock. Thermal dissipation at AC hot state is 4.8 W total, 1.6 W per pole. Surge voltage resistance rated at 6 kV. Relative humidity tolerance up to 100 %.","metaTitle":"Siemens 3RU1116-0GB0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU1116-0GB0 SIRIUS thermal overload relay, Class 10 trip, S00 size, screw terminals, IP20.
