It provides Class 10 motor protection. ## Integration notes Fastens to a SIRIUS S2 contactor via the contactor mounting method — no additional bracket needed. The relay can be rotated ±135° on a vertical mounting surface or tilted ±45° front-to-back, giving flexibility in tight enclosures. Screw terminals on both main and auxiliary circuits accept 2× (0.5…1.5 mm²) solid or stranded, or 2× (0.75…2.5 mm²) with ferrules. Torque the main contacts to 3…4.5 N·m and the auxiliary contacts to 0.8…1.2 N·m. ## Ratings and approvals The auxiliary contacts handle 3 A at 24 V and 2 A at 230 V AC, plus 1 A at 24 V DC-13. The relay is shock-resistant to 8 g / 10 ms per IEC 60068-2-27 and can be installed at altitudes up to 2000 m. Humidity tolerance is 0…90 % RH non-condensing. The design is a thermal bimetallic release — no electronic settings to fail.","metaTitle":"Siemens 3RU7136-4EB0 SIRIUS Thermal Overload Relay, 32 A, Cl","metaDescription":"Siemens 3RU7136-4EB0 SIRIUS thermal overload relay, 32 A rated current, Class 10 trip, 690 V AC/DC.
