This relay mounts directly onto a contactor of size S00 (the smallest SIRIUS frame), so it's a matched set with the contactor beneath it. The main circuit and auxiliary circuit both terminate at screw-type terminals, and the relay supports manual or automatic reset after a trip. This relay is designed to snap onto a size S00 contactor — no separate DIN-rail footprint needed. The width is 45 mm and the depth is 70 mm, which keeps the contactor-plus-relay stack compact. The required spacing to grounded parts at the side is 6 mm, so plan your panel layout with that clearance in mind. Wire entry for the main contacts accepts 2x (0.5…1.5 mm²) solid or stranded, or 2x (0.75…2.5 mm²) with ferrules; auxiliary contacts take similar sizes. Tightening torque for the main screw terminals is 0.8…1.2 N·m — don't overtighten or you'll strip the thread.","metaTitle":"Siemens 3RU6116-0KB0 SIRIUS Overload Relay, 0.9–1.25 A, Clas","metaDescription":"Siemens SIRIUS 3RU6116-0KB0 thermal overload relay, 0.9–1.25 A adjustable, Class 10, size S00.
