Rated insulation voltage is 690 V, covering 400 V and 480 V systems with headroom, and the relay carries motor power ratings at those voltages: 0.09 kW at 400 V, 0.12 kW at 500 V, and 0.12 kW at 690 V. The auxiliary contact ratings span multiple 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 — these are the switching capacities for the signal circuit, not the motor circuit. Temperature compensation is active from -40 °C to +60 °C, meaning the trip curve stays accurate across that ambient range without manual adjustment. The S00 frame size (76 mm high, 45 mm wide, 70 mm deep) is the smallest SIRIUS overload relay footprint, designed to snap onto the matching S00 contactor (e.g., 3RT6015 or 3RT6017 series) without additional wiring between the relay and contactor — the power connections pass through the relay. Terminals accept 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire; screwdriver tip is Pozidriv PZ2 with a 5 to 6 mm shaft diameter. Substance prohibitance per the manufacturer's declaration dates to 10/01/2009, indicating RoHS compliance for that cutoff.","metaTitle":"Siemens 3RU2116-0DB0 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU2116-0DB0 SIRIUS thermal overload relay, CLASS 10, size S00, 690 V rated.

is the closest functional second-source for 3RU2116-0DB0?","answer":"The closest functional peer is the 3RT6017-1AF01 contactor, which shares the S00 frame size and contactor-mounting interface, but the 3RU2116-0DB0 is the overload relay itself — the contactor is a separate component that the relay mounts onto."},{"question":"What does the 'Tripped' note on 3RU2116-0DB0 mean?","answer":"The relay has an integrated auxiliary switch that outputs a signal labeled 'Tripped' when the overload relay has operated, providing a discrete indication to the PLC or control system that the motor circuit has been disconnected due to an overload or phase-failure condition."},{"question":"Will 3RU2116-0DB0 drop into a panel specified around 3RT6017-1AF01 without rewiring?","answer":"Yes, the 3RU2116-0DB0 is designed to mount directly onto S00 contactors like the 3RT6017 series — the power connections pass through the relay and mate with the contactor's terminals, so no additional wiring between the two is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RU2116-0DB0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO
