The IP20 front protection is standard for panel-mounted gear; the relay itself is not rated for washdown environments, so keep it inside the cabinet. That heat has to go somewhere — in a densely packed panel, ensure natural convection paths aren't blocked, or the internal bimetal may drift its trip point over time. The relay is rated for continuous operation from -20 to +70 °C ambient, with storage and transport range from -55 to +80 °C. Shock resistance is specified at 8g for 10 ms, which covers most vibration found in industrial motor control centers. ## Conductor termination and wiring Main circuit connections use cage clamp terminals, accepting solid conductors of 2x (0.5 to 2.5 mm²) or finely stranded with core end processing of 2x (0.5 to 1.5 mm²). AWG equivalents are 2x (24 to 14). The cage clamp provides a vibration-resistant connection without periodic retorquing — a genuine advantage in high-vibration MCC applications where screw terminals can loosen over a few years of thermal cycling. The relay carries ATEX protection type DMT 98 ATEX G 001, certifying it for use in potentially explosive gas atmospheres when installed in an appropriate enclosure. Relative humidity during operation can reach 100 %, including condensation — but the IP20 front means the terminals themselves are not sealed, so the enclosure must handle the condensation.","metaTitle":"Siemens 3RU1116-1GC1 SIRIUS Thermal Overload Relay, CLASS 10","metaDescription":"Siemens 3RU1116-1GC1 SIRIUS thermal overload relay, CLASS 10 trip, S00 frame, 690 V AC-3 max, IP20 front, ATEX certified.
