The thermal bimetallic release tracks motor heating directly — no electronics to fail, no firmware to corrupt (cites:). Temperature compensation holds the trip curve steady from -40 to +60 °C ambient (cites:,). ## Auxiliary contact ratings — what the control circuit sees The integrated auxiliary switch signals the tripped state — the 'Note for message Tripped' on the nameplate tells you this contact changes state when the relay trips (cites:). These are the numbers to use when sizing the PLC input or alarm circuit. The auxiliary is integrated into the relay body — no separate add-on block needed (cites:). Saves a DIN rail slot and one wiring step. ## S00 frame — panel fit and mounting Size S00 means the relay body is 45 mm wide, 76 mm tall, 70 mm deep — it mounts directly onto the contactor, not on the DIN rail (cites:,). The fastening method is contactor mounting: it clips onto the matching S00 contactor and the power connections pass through. Mounting position is any orientation (cites:). The main circuit connections use ring cable lugs with M3 screws (cites:,). Screwdriver tip is Pozidriv PZ2, shaft diameter 5-6 mm (cites:,). Sourced through authorized distribution channels.","metaTitle":"Siemens 3RU2116-0AJ0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU2116-0AJ0 SIRIUS thermal overload relay, Size S00, Trip Class 10.
