Screw-type terminals on the main circuit accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), and up to 2x 4 mm² solid, or 2x (1...2.5 mm²), 2x (2.5...6 mm²), and max 2x 10 mm² stranded. AWG equivalents are 2x (16...12), 2x (14...10), and 1x 8. Size S0 means it's a compact contactor for small to medium motor loads. It can be mounted side-by-side without derating, and the IP20 front protection keeps fingers out during panel access. For short-circuit protection, type 2 coordination requires a 25 A gL/gG fuse; type 1 coordination allows a 63 A gL/gG fuse. The auxiliary contacts (built-in or add-on) are rated for 10 A at 24 V AC, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — enough for PLC inputs or relay coils. ## Sourcing decision If you're filling a BOM line or replacing a failed unit, this part is a direct fit for any panel designed around a SIRIUS S0 contactor. The 45 mm width and screw terminals match the standard footprint.","metaTitle":"Siemens 3RT1023-1AP60 SIRIUS S0 Power Contactor, 400V 4kW","metaDescription":"Siemens SIRIUS 3RT1023-1AP60 power contactor, size S0, 4 kW at 400 V AC-3, 45 mm wide, screw terminals, snap-on DIN rail.

The main difference is the coil voltage — the -1AP60 uses a different coil than the -1AL20. If the coil voltage matches your control circuit, it's a mechanical and electrical drop-in.
