Rated operational current is 1.25 A, with trip class 10 — meaning it will trip within 10 seconds at 7.2× the set current, fast enough to protect standard induction motors without nuisance tripping during start-up. Rated voltage is 690 V AC/DC, 50/60 Hz. The 1.25 A rated current sets the upper limit of the adjustable overload range — this relay is sized for small motors, pumps, or fans drawing roughly 1 A full-load. Trip class 10 is the standard for general-purpose motor starting; if your application has a long acceleration time (centrifuges, high-inertia loads), you would typically step to class 20. Auxiliary contact ratings: 3 A at 24 V, 2 A at 230 V, and 1 A at 24 V DC-13 for the control circuit. These are the contacts that signal the contactor coil or PLC input on a trip event — verify your control voltage and load type against these numbers. Fastens directly to a S00 contactor (contactor mounting) — no separate base required. Mounting position allows vertical surface with ±135° rotation and ±45° tilt front/back, giving flexibility in tight panels. Side spacing to grounded parts must be at least 6 mm. Accepts 2× (0.5…1.5 mm²) or 2× (0.75…2.5 mm²) solid/stranded, or finely stranded with ferrule. Terminal torque: 0.8…1.2 N·m for both main and auxiliary contacts.","metaTitle":"Siemens 3RU7116-0KB0 SIRIUS Thermal Overload Relay, 1.25 A,","metaDescription":"Siemens SIRIUS 3RU7116-0KB0 thermal overload relay, size S00, rated 1.25 A, trip class 10, for contactor mounting.
