It fastens via screw or snap-on onto standard 35 mm DIN rail, so it drops into the same panel footprint as other SIRIUS S2 components without re-drilling the backplate. ## Wire Range and Termination — Main Circuit The screw terminals accept 1x (1 to 50 mm²) solid or stranded copper, plus 1x (18 to 1 AWG) — covering the common motor-circuit conductor sizes up to 50 mm² without needing a ferrule. For finely stranded wire with core-end processing, the range is 1x (1 to 35 mm²), which handles flexible cable in control-panel wiring. ## Footprint and Environmental Limits The enclosure measures 55 mm wide by 105 mm high by 111 mm deep — a compact S2 envelope that fits alongside contactors in a standard 400 mm-deep enclosure with room for the outgoing cables. Rated for operation from -20 to +70 °C and storage from -50 to +80 °C, so it handles the thermal extremes in a non-climate-controlled cabinet near a motor.","metaTitle":"Siemens 3RU5936-3AA01 SIRIUS Overload Relay, Size S2","metaDescription":"Siemens 3RU5936-3AA01 SIRIUS overload relay, Size S2, 55x105x111 mm, screw terminals, 1x (1...50 mm²) solid/stranded.
