For across-the-line starting of cage motors (AC-3) you'd use the higher current capability implicit in the AC-2/AC-4 mix; the 4 kW AC-2 rating at 400 V covers slip-ring motor duty. For Type 1 coordination (contactor may need replacement after fault) the fuse can go up to 63 A. Side-by-side mounting is permitted — no derating gap required. The front face carries IP20 protection; the terminals themselves are rated IP00, so panel builders should allow clearance around live parts.","metaTitle":"Siemens 3RT1023-3AG60 SIRIUS Power Contactor, S0, 8.5 A AC-4","metaDescription":"Siemens SIRIUS 3RT1023-3AG60 power contactor, S0 frame, 8.5 A AC-4 at 400 V, 4 kW AC-2, 5.5 kW at 690 V.
