It carries AC-2 and AC-4 ratings at 400 V (5.5 kW and 12.5 A respectively), so it handles both slip-ring motor starting and plugging/inching duty. The built-in RC surge suppressor means you don't need an external snubber for coil suppression — one less part to panel-mount. The 45 mm width and 88 mm height fit standard S0 panel layouts. Side-by-side mounting is allowed with zero clearance between units — no derating for adjacent contactors in the same row. ## Terminal and wiring Screw-type terminals on the main circuit accept 2x (0.25...2.5 mm²) solid, 2x (1...2.5 mm²) stranded, 2x (2.5...6 mm²) stranded, or up to 2x 10 mm². AWG equivalents are 2x (16...12), 2x (14...10), or 1x 8. The auxiliary contacts are rated at 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V — covering control circuits across common voltage levels.","metaTitle":"Siemens SIRIUS 3RT1024-3EG24 Power Contactor, S0, 110 V 50/6","metaDescription":"Siemens SIRIUS 3RT1024-3EG24 power contactor, size S0, 110 V 50/60 Hz coil, 7.5 kW at 690 V, screw terminals, RC suppressor, IP20 front.
