Rated for 400 V at 50 Hz and 400 to 440 V at 60 Hz, this contactor delivers 4.5 kW at 500 V and 5.5 kW at 690 V. The 24 V DC coil draws 10 A, and the AC-4 rating at 400 V is 8.5 A — the value that governs switching of motor loads under inrush and plugging conditions, not the steady-state AC-1 figure. ## Coordination and wiring Main circuit terminals accept screw-type connections: solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²); stranded conductors 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8.","metaTitle":"Siemens 3RT1023-1AR60 SIRIUS Power Contactor, S0, 400 V 50 H","metaDescription":"Siemens SIRIUS 3RT1023-1AR60 power contactor, size S0, 400 V 50 Hz, 10 A at 24 V, 4.5 kW at 500 V, 5.5 kW at 690 V, AC-4 8.5 A at 400 V.
