It protects AC motors against overload and phase failure. The footprint is 45 mm wide, 87 mm high, and 78 mm deep — a standard S00 envelope that shares the same mounting hole pattern as the matching SIRIUS contactor (the 3RT10 series). Clearance requirements are minimal: 0 mm spacing upwards, forwards, backwards, and downwards, with only 6 mm needed at the side. Both the main current circuit and the auxiliary/control circuit use screw-type terminals. The main contacts accept solid conductors 1x (20...16 AWG), 1x (18...14 AWG), or 1x 12 AWG, and finely stranded with core end processing 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²). The Class 10 trip characteristic is the key selection parameter. It means the relay clears a locked-rotor condition before the motor winding insulation reaches its thermal limit, but it's not so fast that it trips on a normal start. If your motor's acceleration time exceeds 10 seconds at full voltage, you need a Class 20 or 30 relay instead.","metaTitle":"Siemens 3RU1116-1EB1 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens SIRIUS 3RU1116-1EB1 thermal overload relay, Class 10 trip, Size S00, 690V AC-3 max.
