Rated insulation voltage is 690 V, and it covers motor power ratings up to 7.5 kW at 400 V and 11 kW at 690 V. The integrated auxiliary switch on this relay is rated for several common control voltages. At 24 V it switches 2 A; at 120 V it handles 3 A; at 230 V it's rated 2 A; and at 400 V it drops to 1 A. For DC control circuits, it's rated 0.3 A at 60 V and 0.22 A at 110/125 V. These are the maximum continuous make-and-break ratings — if you're driving a PLC input or a contactor coil, stay under these values to avoid welding the contacts. The auxiliary is integrated, so there's no separate switch block to order. ## Mounting and Wiring — Standalone, Spring-Loaded Terminals This relay mounts standalone — no DIN rail adapter required, though it can be snapped onto a contactor if needed. The spring-loaded terminals on the main circuit accept 2× (0.5 to 2.5 mm²) solid or stranded wire. The auxiliary switch uses the same terminal type. A 3 mm screwdriver shaft is specified for the terminal screws on the auxiliary side. MTTF with high demand rate is 2,280 years.","metaTitle":"Siemens 3RU2116-4AC1 SIRIUS Thermal Overload Relay, Size S00","metaDescription":"Siemens 3RU2116-4AC1 SIRIUS thermal overload relay, Size S00, Trip Class 10, rated 690V.
