It is the component that monitors motor current and trips the contactor on overload, sized for the SIRIUS S2 frame. The 55 mm width and 118 mm depth match the SIRIUS S2 contactor footprint; it mounts directly onto the contactor (contactor mounting, no extra DIN rail space). IP20 on the front protects against finger contact. The ATEX marking (DMT 98 ATEX G 001) confirms suitability for gas Group II, Category 2G equipment. Surge voltage resistance rated at 6 kV. The 100 % relative humidity rating during operation indicates it can run in condensing environments. ## Wiring and integration Main circuit terminals accept solid conductors from 2x (0.5... 1.5 mm²) to 2x (0.75... 2.5 mm²); stranded up to 2x (0.75... 25 mm²) or single 0.75... 35 mm². Auxiliary and control circuit terminals are also screw-type, accepting 2x (0.5... 1.5 mm²) solid or finely stranded with ferrule. AWG equivalents: main 2x (18... 3) or single 18... 1; auxiliary 2x (20... 16) or 2x (18... 14). Mounting position allows vertical surface with ±135° rotation or ±45° tilt forward/back. Zero clearance required upwards, forwards, and backwards; 6 mm side clearance. Shock resistance 8g / 10 ms.","metaTitle":"3RU1136-4HB0-ZW96 SIRIUS Thermal Overload Relay, Class 10, 5","metaDescription":"Siemens SIRIUS 3RU1136-4HB0-ZW96 thermal overload relay, Class 10 trip, ATEX certified, IP20 front.
