Siemens 3RU2116-0JC1 is a SIRIUS thermal overload relay, size S00, Class 10 trip, rated 690 V insulation voltage.
The integrated auxiliary switch provides signal contacts rated across common control voltages: 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. Lower-voltage DC ratings include 0.3 A at 60 V and 0.22 A at 125 V. These cover most PLC input and contactor coil feedback circuits.
Mounts in any position with spring-loaded terminals for the main circuit — no screw torque needed, just a 3 mm screwdriver for the auxiliary terminals. Accepts 2 × (0.5…2.5 mm²) solid or stranded wire. Dimensions are 45 mm wide, 102 mm high, 79 mm deep — fits standard 45 mm DIN-rail footprint for size S00.
