The CLASS 10 trip class means it will trip within 10 seconds at 7.2× the set current — fast enough to protect standard squirrel-cage motors against locked-rotor conditions without nuisance tripping during normal starting. Rated voltage is 690 V, with motor power ratings of 0.55 kW at 400 V, 0.75 kW at 500 V, and 1.1 kW at 690 V. The auxiliary contact provides a dedicated 'Tripped' signal — it closes on overload, giving the PLC or annunciator a clean status bit without extra wiring. The relay measures 87 mm high, 45 mm wide, and 70 mm deep — a compact footprint that fits the S00 contactor width, so it doesn't eat extra DIN rail space. Mounting position is any orientation, which simplifies panel layout in tight enclosures. ## Auxiliary contact ratings and wiring The integrated auxiliary switch carries 2 A at 24 V, 3 A at 120 V, and 2 A at 230 V — enough to drive a PLC input or a small relay directly. At 400 V it's rated 1 A, and at 690 V it drops to 0.75 A. The contact is a single-pole changeover, so you get both NO and NC from the same block. Terminals are spring-loaded (cage clamp), accepting 2× 0.5 to 2.5 mm² solid or stranded wire. No screw torque to check — strip, push, done. The screwdriver slot is 3.0 × 0.5 mm for the release lever. ## Environmental range and compensation Operating temperature is -40 to +70 °C, with temperature compensation active over -40 to +60 °C — the relay self-adjusts for ambient changes so the trip point stays accurate whether the panel is in a heated factory or a cold warehouse. Storage and transport range is -55 to +80 °C. MTTF at high demand rate is 2,280 years — a reliability figure that supports safety-related applications where the relay is cycled frequently. The substance prohibition date of 10/01/2009 indicates RoHS compliance per the original EU directive.","metaTitle":"Siemens 3RU2116-1AC0-ZX95 SIRIUS Thermal Overload Relay","metaDescription":"Siemens 3RU2116-1AC0-ZX95 SIRIUS thermal overload relay, CLASS 10, 690 V rated, 87x45x70 mm, S00 size.
