The relay uses a thermal bimetallic release, so it tracks the motor's true thermal state, not just a fixed curve. It clips directly onto the contactor — no separate DIN-rail footprint needed — and the auxiliary switch is integrated into the housing, saving panel space. At 24 V it switches 2 A; at 120 V it handles 3 A; at 230 V it's 2 A; and at 400 V it's 1 A. These are the auxiliary contact ratings for the trip-indicating circuit — the note \"for message 'Tripped'\" means this variant includes a remote signal contact that changes state when the relay trips, so a PLC or HMI can log the fault. Temperature compensation is active from -40 °C to +60 °C, so the trip curve stays accurate across most industrial environments. The relay carries a substance prohibitance date of 10/01/2009, indicating RoHS compliance per EU Directive 2002/95/EC. It is part of the SIRIUS family, which typically holds UL, CSA, and CE certifications — verify the specific approvals on the nameplate for your jurisdiction, but the platform is globally accepted.","metaTitle":"Siemens 3RU2116-1BB0-ZW97 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens SIRIUS 3RU2116-1BB0-ZW97 thermal overload relay, Size S00, Class 10 trip.

They are not direct drop-in replacements without rewiring the motor branch circuit."},{"question":"What is the depth of the 3RU2116-1BB0-ZW97?","answer":"The depth is 70 mm, width 45 mm, height 76 mm. This is the Size S00 frame, which mounts directly on SIRIUS 3RT2 contactors without extra DIN-rail space."},{"question":"Will the 3RU2116-1BB0-ZW97 drop into a panel specified around the 3RV1011-1HA10?","answer":"No, not without rewiring. The 3RV1011-1HA10 is a motor starter protector that combines a circuit breaker and overload relay in one unit, wired directly to the motor. The 3RU2116 is a thermal overload relay that mounts on a contactor and requires a separate upstream short-circuit protection device. The footprint is similar (both S00 frame), but the circuit topology is different."},{"question":"What compliance documentation is available for the 3RU2116-1BB0-ZW97?","answer":"The relay has a substance prohibitance date of 10/01/2009, indicating RoHS compliance.
