Rated for 690 V (the maximum operating voltage of the main circuit), it carries a motor power rating of 2.2 kW at 400 V, 3 kW at 500 V, and 4 kW at 690 V — the power step-up reflects the lower current draw at higher voltage for the same motor kW. The auxiliary switch is integrated, and the relay uses screw-type terminals for the main circuit, accepting 2 × (0.5 to 1.5 mm²) or 2 × (0.75 to 2.5 mm²) solid or stranded wire. Mounting is stand-alone (not DIN-rail clip-on) in any position, with dimensions 80 mm deep, 45 mm wide, and 89 mm tall — the S00 footprint matches the corresponding SIRIUS contactor frame for a direct mechanical link. ## Integration notes Terminal screws use a Pozidriv PZ 2 tip; the screwdriver shaft diameter should be 5 to 6 mm. The relay compensates for ambient temperature changes from -40 °C to +60 °C, so it tracks the motor's thermal state rather than the panel's internal temperature. The listed 'Note for message Tripped' indicates the relay's auxiliary contact signals a trip condition — this is the NC contact that opens when the relay trips, used in the control circuit to drop out the contactor coil.","metaTitle":"Siemens 3RU2116-1GB1 SIRIUS thermal overload relay, S00, CLA","metaDescription":"Siemens 3RU2116-1GB1 SIRIUS thermal overload relay, S00 frame, CLASS 10 trip, 690 V rated, 2.2 kW at 400 V.
