The 10 A rated operational current at AC-12 (resistive) gives a ceiling for control-circuit switching. Main terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²) solid, or 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm² stranded. Auxiliary terminals share the same screw-clamp design, simplifying wiring across the panel. IP20 on the front, IP00 at the terminals — the terminal area is unprotected, so it requires enclosure clearance from live parts. For coordination, a gL/gG fuse of 25 A meets type 2 coordination requirements; a 63 A fuse meets type 1.","metaTitle":"Siemens 3RT1023-1AK60 SIRIUS Power Contactor, S0, 4 kW at 40","metaDescription":"Siemens SIRIUS 3RT1023-1AK60 power contactor, size S0, 45 mm wide.
