It mounts directly onto a contactor, saving DIN-rail space — the 45 mm width and 78 mm depth fit the S00 footprint common across the SIRIUS line. Screw-type terminals on both main and auxiliary circuits simplify wiring with solid or finely stranded conductors: 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²) per terminal. Mounts on the contactor with zero clearance needed upwards, forwards, backwards, or downwards — the relay shares the contactor's footprint. Side clearance to adjacent devices is 6 mm. The mounting position allows a vertical surface with ±135° rotation and ±45° tilt front-to-back, giving flexibility in tight enclosures. IP20 on the front and finger-safe touch protection keep live parts guarded during panel access. ## Electrical ratings and trip class Auxiliary contact ratings: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V. The relay handles 100 % relative humidity during operation and operates from -20 to +70 °C, with storage and transport range of -55 to +80 °C. Shock resistance is 8g for 10 ms.","metaTitle":"Siemens 3RU1116-0KB0-ZW98 thermal overload relay, SIRIUS S00","metaDescription":"Siemens SIRIUS 3RU1116-0KB0-ZW98 thermal overload relay, Size S00, Trip Class 10, 45 mm wide, contactor mounting.
