Siemens 3RU1116-0EB1 is a SIRIUS thermal overload relay, size S00, CLASS 10 trip protection. Rated for stand-alone installation, the relay mounts on a vertical surface with ±135° rotation and ±45° tilt flexibility, simplifying panel layout. The IP20 front enclosure keeps live parts behind the panel door. Main-circuit connections use screw-type terminals accepting 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) finely stranded with ferrules, matching standard control wiring practice.
Integration and Mounting
Panel footprint is 45 mm wide × 87 mm high × 78 mm deep — a compact S00 frame that fits standard 45 mm DIN-rail spacing when used with a matching contactor. Clearance: 0 mm upwards, forwards, backwards, and downwards; 6 mm at the side. The relay includes DMT 98 ATEX G 001 protection type, qualifying it for use in potentially explosive atmospheres where temperature class and ignition protection are specified.
Electrical Ratings
Maximum operating voltage in AC-3 duty is 690 V. Thermal dissipation at AC hot operating state is 4.8 W total, 1.6 W per pole — relevant for enclosure temperature rise calculations. Surge voltage resistance is rated at 6 kV, and shock resistance is 8 g / 10 ms, adequate for industrial panel environments with moderate vibration. Ambient operating range is −20 to +70 °C, storage and transport range −55 to +80 °C, with 100 % relative humidity tolerance during operation.
