The relay mounts directly onto a S00 contactor, saving panel space and wiring. This relay is designed for contactor mounting onto a S00 frame contactor, not for standalone DIN-rail installation. The mounting position allows ±135° rotation and ±45° tilt forward/back from vertical, giving flexibility in tight enclosures. Dimensions are 78 mm deep, 45 mm wide, and 87 mm tall — the width is the critical panel-space number when ganging multiple relays on adjacent contactors. The screw-type terminals on both main and auxiliary circuits accept 2× (0.5…1.5 mm²) solid or 2× (0.75…2.5 mm²) stranded, with a tightening torque of 0.8…1.2 N·m. Side spacing to grounded parts needs 6 mm minimum. The 0.16 A rated operational current sets the motor FLA this relay protects — it's for very small motors, fractional-horsepower fans, or small pumps. The Trip Class 10 ensures nuisance-free starting for motors with normal inertia while still protecting against locked-rotor conditions. Total typical power loss is 4.8 W, which matters for thermal management inside a sealed enclosure. The auxiliary contacts are rated 1 A at DC-13, 24 V, enough for signaling to a PLC input. The relay is rated for installation altitudes up to 2 000 m.","metaTitle":"Siemens 3RU7116-0AB0 SIRIUS Thermal Overload Relay, Size S00","metaDescription":"Siemens 3RU7116-0AB0 SIRIUS thermal overload relay, Size S00, 0.16 A rated current, Trip Class 10, 690 V, 50/60 Hz.
