Its 12 A rated operational current and Class 10 trip curve mean it responds fast enough to guard standard induction motors against overload without nuisance tripping on startup inrush. The relay mounts directly to a contactor of the same S00 frame — no separate DIN-rail bracket needed — and the screw-type main and auxiliary terminals accept 2x (0.75... 2.5 mm²) solid or stranded wire. Fastening is contactor mounting — the relay clips onto the S00 contactor (e.g. 3RT1016 series) without extra hardware. The mounting position allows vertical surface installation with ±135° rotation and ±45° tilt front/back. Spacing of 6 mm to grounded parts at the side keeps heat dissipation in check. Dimensions: 45 mm wide, 87 mm high, 78 mm deep — fits standard panel layouts.","metaTitle":"Siemens 3RU7116-1KB0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU7116-1KB0 SIRIUS thermal overload relay, size S00, 12 A rated current, Class 10 trip, 690 V.
