It protects three-phase motor circuits against overload and phase failure. It mounts directly onto a contactor (fastening method: contactor mounting), saving panel space and wiring. The mounting position allows ±135° rotation and ±45° tilt on a vertical surface, giving flexibility in tight enclosures. For environments with washdown or condensation, it needs a separate enclosure. RoHS compliance is documented with a substance prohibition date of 07/01/2006. Dimensions: 45 mm wide, 87 mm high, 78 mm deep. Side clearance of 6 mm is required for heat dissipation; zero clearance needed upwards, forwards, backwards, or downwards. Main circuit terminals accept screw-type connections: 2× (0.5…1.5 mm²) solid or 2× (0.75…2.5 mm²) stranded, plus AWG equivalents 2× (20…16) and 2× (18…14). Auxiliary and control circuit terminals use the same screw-type format with 2× (20…16) and 2× (18…14) AWG. Power dissipation per pole is 2.2 W, totaling 6.6 W for the three-pole unit at rated current. This heat must be considered in enclosure sizing, especially when grouped with other devices. Shock resistance is rated at 8g for 10 ms, adequate for most industrial machinery but not for high-impact applications like forging presses without additional damping. The built-in auxiliary contacts are rated for switching: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V (AC), plus 0.22 A at 110 V, 0.22 A at 125 V, and 0.11 A at 220 V (DC). These are the maximum switching capacities — derate for inductive loads or high inrush.","metaTitle":"Siemens 3RU1116-1FB0-ZW97 SIRIUS Thermal Overload Relay, Siz","metaDescription":"Siemens 3RU1116-1FB0-ZW97 SIRIUS thermal overload relay, Size S00, CLASS 10 trip, IP20 front, ATEX approved, current production.
