Rated operational current is 2.5 A at 690 V, 50/60 Hz, making it suitable for small motor branches in control panels and motor control centers. Designed for stand-alone installation — it mounts independently, not directly on a contactor coil, so you need to wire it between the contactor and the motor. Fastening method is stand-alone, and mounting position is any orientation. Width is 45 mm and depth is 80 mm, fitting a standard DIN-rail footprint for size S00 components. Required spacing to grounded parts at the side is 6 mm — factor that into your panel layout. Main circuit connections are screw-type terminals, top and bottom, accepting 2×(0.5…1.5 mm²) solid/stranded or 2×(0.75…2.5 mm²) finely stranded with ferrules. Tightening torque is 0.8…1.2 N·m. Compliance documentation includes RoHS compliance with substance prohibition date of May 1, 2012, and the relay carries a 6 kV surge voltage resistance rating per IEC 60947.","metaTitle":"Siemens 3RU6116-1CB1 SIRIUS Thermal Overload Relay, 1.8-2.5","metaDescription":"Siemens SIRIUS 3RU6116-1CB1 thermal overload relay, adjustable 1.8-2.5 A, Class 10 trip, size S00, screw terminals, stand-alone mount, 45 mm wide, 80 mm deep.
