That's the curve you want for standard induction motors driving pumps, fans, or conveyors where the start-up time is short. The relay is rated for main circuits up to 690 V, and at 400 V it handles 22 kW motor loads. It carries a 45 A rating at 480 V and 600 V, and 37 kW at 690 V. The auxiliary contacts are rated for 2 A at 24 V, 3 A at 120 V, and 1 A at 400 V — enough to signal a PLC input or a status lamp. This relay is designed for stand-alone installation — it does not require a dedicated base or adapter. It mounts in any position, which helps when you're fitting it into a tight panel. The main circuit terminals accept screw-type connections, and the terminal screws take a Pozidriv PZ2 bit or a 5–6 mm diameter shaft. Dimensions are 55 mm wide, 105 mm tall, and 117 mm deep — a compact footprint for a size S2 relay, so it fits in a standard 55 mm DIN-rail slot if you're using an adapter base (not included). The auxiliary switch is integrated into the housing, no extra module needed. Temperature compensation is active from –40 to +60 °C, so the trip curve stays accurate across the working range.","metaTitle":"Siemens 3RU2136-4GB1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2136-4GB1 SIRIUS thermal overload relay, CLASS 10, rated 690 V, 22 kW at 400 V.
