It mounts directly onto S00-frame contactors — no DIN-rail space needed, just snap it onto the contactor and wire the main circuit through its screw-type terminals top and bottom. The 3.5 to 5 A adjustable current-response value means you set the trip point to match the motor full-load amps within that window — no swapping heaters. Class 10 trip gives a 10-second maximum lock-rotor time at 7.2× Ie, which protects standard IEC motors without nuisance tripping on start. ## Terminals and wiring Main circuit terminals are screw-type, top and bottom, accepting 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded copper. Torque them to 0.8 to 1.2 N·m — enough for a solid connection without stripping the head. Auxiliary and control circuit terminals are also screw-type, same wire ranges. ## Environmental and installation limits Mount it in any position, but leave 6 mm clearance to grounded parts on the side for heat dissipation.","metaTitle":"Siemens 3RU6116-1FB0 SIRIUS Thermal Overload Relay, 3.5-5 A,","metaDescription":"Siemens SIRIUS 3RU6116-1FB0 thermal overload relay, 3.5-5 A adjustable, Class 10, screw terminals.
