The AC-4 switching current at 400 V is 12.5 A, covering demanding reversing or inching duty cycles. The 45 mm width and 85 mm height fit standard S0 panel layouts; depth is 101 mm. Side-by-side mounting is allowed with a 6 mm gap to adjacent devices for thermal dissipation. For type 1 coordination (contactor may need replacement after fault), the fuse can go up to 63 A.","metaTitle":"Siemens 3RT1024-1BB40-ZW96 SIRIUS Power Contactor, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1024-1BB40-ZW96 power contactor, size S0, 24 VDC coil, 7.5 kW at 690 V.
