It protects motors against overload and phase failure, rated for main circuits up to 690 V. The thermal bimetal release is temperature-compensated from -40 to +60 °C, so the trip point stays stable across a typical panel ambient range. The 690 V rated value covers 400 V and 480 V systems with headroom; the power ratings at 400 V (37 kW) and 500 V (55 kW) give a quick sizing reference for common line voltages. The auxiliary switch is integrated, so no separate add-on block is needed for the trip signal. The note \"for message 'Tripped'\" on the relay indicates that the auxiliary contact position changes when the overload trips — that's the signal you wire back to the PLC or annunciator. The main contact terminals take M6 screws; the auxiliary circuit terminals accept 2× (0.5 to 2.5 mm²) solid or stranded wire. At 55 mm wide and 117 mm deep, it fits a standard DIN-rail enclosure with room for adjacent contactors or busbars.","metaTitle":"Siemens 3RU2136-4RD1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2136-4RD1 SIRIUS thermal overload relay, Class 10A, rated 690 V, 55 mm wide.
