Rated operational current is 6.3 A at 690 V operating voltage, 50-60 Hz. ## Panel integration — S00 frame, 45 mm wide, any mounting position The 3RU6116-1GB1 occupies the S00 contactor frame size, meaning it directly couples to Siemens S00 contactors without additional adapters. Width is 45 mm, depth 80 mm, height 89 mm — fits standard 45 mm grid DIN-rail or panel-mount layouts. Mounting position is any orientation; fastening method is stand-alone installation. Required spacing to grounded parts at the side is 6 mm. The relay can be installed at altitudes up to 2000 m above sea level. Auxiliary contacts accept 2x (20-16) and 2x (18-14) AWG. Tightening torque for main screw terminals is 0.8-1.2 N·m. ## Thermal dissipation and environmental limits Total typical power loss is 5.7 W; at rated current in AC hot operating state, power loss is 6.6 W. Per-pole loss is 2.2 W. These figures matter for panel thermal budget — in a densely packed enclosure, the 6.6 W ceiling should be included in the enclosure's heat rise calculation. Relative humidity during operation is 0 to 90 %. The relay withstands 8g / 11 ms shock per IEC 60068-2-27. Insulation voltage at degree of pollution 3 is 690 V AC; surge voltage resistance is 6 kV — coordinates with standard 400/480 VAC motor circuits. ## Auxiliary contact ratings and control circuit compatibility These are the continuous current ratings for the control circuit — confirm the PLC output or relay driving the auxiliary loop does not exceed these limits. The auxiliary circuit uses screw-type terminals with the same wire ranges as the main circuit. Substance prohibitance date is 05/01/2012 — consistent with RoHS compliance for the EU RoHS recast (2011/65/EU). The relay carries the SIRIUS brand and is designed to IEC/EN 60947-4-1 for motor starters and overload protection.","metaTitle":"Siemens 3RU6116-1GB1 SIRIUS Thermal Overload Relay","metaDescription":"Siemens 3RU6116-1GB1 SIRIUS thermal overload relay, 4.5-6.3 A adjustable range, Class 10 trip, size S00.
