Product details

The Siemens 3RU7136-4EB0 is a SIRIUS thermal overload relay in size S2, rated for 32 A operational current and 690 V AC/DC. 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.

Frequently asked questions

What are the key dimensions?

Width 55 mm, height 105 mm, depth 118 mm. These are the body dimensions for panel layout and DIN-rail spacing.

What compliance documentation is available?

The relay carries IEC ratings (IEC 60947-4-1) and is designed for global use. Specific UL/CSA/CE/UKCA/EAC marks are not listed in the available spec data, but as a standard Siemens SIRIUS component it typically holds multiple national approvals. Request the specific declaration of conformity or certificate with your RFQ.
