The relay handles switching across a wide voltage range: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. This covers most control-circuit voltages found in industrial installations. Fastens directly to a contactor (contactor mounting), eliminating separate DIN-rail space and wiring. Main circuit connections use spring-loaded terminals, accepting 2x (0.5 to 2.5 mm²) solid or stranded wire. This speeds panel wiring and resists loosening under vibration. Temperature compensation is active from -40 to +60 °C, ensuring accurate trip characteristics across the working range. Substance prohibitance dated 10/01/2009 indicates RoHS compliance for the European market. ## Sourcing posture No last-time-buy or phase-out constraints apply. The integrated auxiliary switch and thermal release design mean this is a direct-fit replacement for existing S00 overload relay slots in Siemens contactor assemblies.","metaTitle":"Siemens 3RU2116-1BC0 SIRIUS thermal overload relay, S00, CLA","metaDescription":"Siemens 3RU2116-1BC0 SIRIUS thermal overload relay, size S00, CLASS 10 trip, 690 V rated, spring-loaded terminals.
