The relay mounts in any position and uses spring-loaded terminals for the main circuit, accepting 2x (0.5... 2.5 mm²) solid or stranded wire. Rated insulation voltage is 690 V, with AC-3e rated maximum at the same 690 V — this relay is suitable for 400 V, 480 V, 500 V, and 690 V motor circuits. Motor power ratings are given at several voltages: 0.55 kW at 400 V, 0.75 kW at 500 V, and 1.1 kW at 690 V. The integrated auxiliary switch (one N/O + one N/C) carries 2 A at 24 V, 2 A at 230 V, 1 A at 400 V, and 3 A at 120 V — enough to signal a trip to a PLC input or drop out a contactor coil. Power loss per pole is 1.9 W, which matters for thermal buildup in a crowded panel. ## Deployment Context This relay is designed for stand-alone installation — it does not require a separate base or contactor mounting. Temperature compensation is active from -40 to +60 °C, so the trip curve stays accurate across the operating range of most industrial enclosures.","metaTitle":"Siemens 3RU2116-1AC1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-1AC1 SIRIUS thermal overload relay, Class 10, size S00, 690 V rated, spring-loaded terminals.
