The 45 mm width and 76 mm height match the S00 contactor footprint, so the assembly stays within a single modular width in the panel. Fastening method is contactor mounting, meaning it clips onto the contactor's base; verify the contactor model supports S00 add-ons before committing the BOM line. Screw-type terminals on both main and auxiliary circuits accept 2× (0.5 to 1.5 mm²) solid or 2× (0.75 to 2.5 mm²) stranded, with AWG equivalents of 2× (20 to 16) for mains and 2× (20 to 16) for aux. Tightening torque for main contacts is 0.8 to 1.2 N·m — use a torque screwdriver; overtightening can strip the terminal on the S00 body. Required spacing to grounded parts at the side is 6 mm — tight, but check that clearance if the relay sits next to a grounded busbar or enclosure wall. Relative humidity during operation is 0 to 90 %. Installation altitude is limited to 2,000 m above sea level — above that, derate the current rating per IEC 60947. The relay carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance from that date forward. Surge voltage resistance is rated at 6 kV, and insulation voltage at AC is 690 V with pollution degree 3. Shock resistance per IEC 60068-2-27 is 8g for 11 ms — adequate for most industrial panel environments but not for high-vibration applications like direct engine mounting.","metaTitle":"Siemens 3RU6116-0HB0 SIRIUS Thermal Overload Relay, 0.55-0.8","metaDescription":"Siemens SIRIUS 3RU6116-0HB0 thermal overload relay, 0.55-0.80 A adjustable, Class 10 trip, size S00 for contactor mounting.
