It includes a factory-fitted auxiliary contact block (1 NO + 1 NC) and is rated for AC-3 motor starting duty. Typical applications include control cabinet retrofits, motor control centers, and spare replacement for aging S0-size contactors in industrial panels. Panel cutout planning: the contactor measures 97 mm depth, 45 mm width, and 85 mm height. It snaps onto a 35 mm DIN rail per EN 60715 and can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward. Minimum clearances: 10 mm upward, forward, and downward; 6 mm to the side. Derating may apply if these gaps are reduced. The auxiliary contact terminals handle 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. Screw-type connections; ferrules recommended for fine-stranded wire but not mandatory within the listed range. ## Environmental Ratings Suitable for indoor control cabinets without condensation.","metaTitle":"Siemens 3RT2024-1AF00 SIRIUS Power Contactor, S0, 110V AC Coil, 3 Pole","metaDescription":"Siemens 3RT2024-1AF00 SIRIUS power contactor, size S0, 3-pole, screw terminals, 1 NO+1 NC auxiliary contacts.
