The S0 frame measures 45 mm wide by 85 mm high by 90 mm deep, so it fits standard 45 mm DIN-rail pitch. DC switching capability is specified per voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V. The screw terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, up to 2x 10 mm² max — covers most control and power wiring in a standard panel. Fuse coordination: with type 2 coordination (no welding on short circuit), use gL/gG 25 A fuses; with type 1 coordination (allow contactor replacement after fault), use gL/gG 63 A fuses. This is the spec your panel designer needs for the short-circuit protection scheme.","metaTitle":"Siemens 3RT1024-3AL20-ZX95 SIRIUS Contactor, S0 Size, 45mm","metaDescription":"Siemens SIRIUS 3RT1024-3AL20-ZX95 power contactor, S0 size, 45mm width, 90mm depth, screw terminals, 35mm DIN rail mount.
