At 400 V it carries 37 kW motor load; at 690 V that rises to 75 kW. The auxiliary contact ratings cover a wide control-voltage range — 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, 0.75 A at 690 V — so it can directly drive a PLC input or a contactor coil without an interposing relay in most panels. Per-pole power dissipation is 6.3 W, which matters for enclosure heat buildup if the relay is grouped with other devices. Mounts in any position — no derating for sideways or inverted installation. Dimensions are 55 mm wide, 105 mm high, 117 mm deep, so it fits a standard 55 mm-wide DIN-rail footprint (S2 frame). Main circuit terminals accept 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²); use a Pozidriv PZ 2 screwdriver with a 5–6 mm shaft diameter. The M6 main-contact bolts are sized for the S2 current range. Temperature compensation is active from -40 °C to +60 °C, so the trip curve stays accurate even in an unheated enclosure.","metaTitle":"Siemens 3RU2136-4RB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2136-4RB1 SIRIUS thermal overload relay, CLASS 10A, rated 690 V.
