It mounts directly to a contactor and protects AC motors against overload and phase failure. The relay mounts directly onto the contactor via the contactor mounting fastening method, eliminating separate DIN-rail space and wiring between the contactor and overload. Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire — a standard range for motor feeders up to the S00 frame rating. The auxiliary contact (integrated design) switches 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 — these are the make/break capacities for the trip-indication circuit, not the main motor current. The note 'for message Tripped' confirms the auxiliary contact signals the tripped state, so it is wired into the PLC or alarm circuit, not the motor power path. The relay is temperature-compensated from -40 to +60 °C, meaning the trip curve stays within tolerance across that ambient range — important for panels near ovens, outdoors, or in unheated enclosures. Mounting position is any, so the relay can be installed horizontally or vertically without derating. Substance prohibition date of 10/01/2009 indicates RoHS compliance per the EU directive. ## Integration note Mounts directly to a Siemens contactor of matching S00 frame size — no separate DIN-rail clip needed. The auxiliary contact is integrated, so no add-on block is required for the tripped signal. Screw terminals accept Pozidriv PZ2 screwdriver tip (shaft diameter 5 to 6 mm).","metaTitle":"Siemens 3RU2116-1BB0 SIRIUS Thermal Overload Relay, S00, Cla","metaDescription":"Siemens SIRIUS 3RU2116-1BB0 thermal overload relay, size S00, Class 10 trip, 690 V rated, contactor-mount.
