For resistive loads (AC-12), the maximum operational current is 10 A. The screw terminals accept solid conductors from 0.5 to 1.5 mm² (two per clamp) and stranded up to 2.5 mm² (two per clamp), with a maximum of two 4 mm² solid wires. For the main circuit, stranded wire up to 6 mm² (two per clamp) or a single 10 mm² is allowed. AWG equivalents are 16–12 for solid, 14–10 for stranded, and a single 8 AWG. The auxiliary contacts accept 20–16 AWG solid or 18–14 AWG stranded, with a single 12 AWG maximum. This covers most panel wiring up to moderate motor loads. The size S0 frame keeps the panel density high.","metaTitle":"Siemens 3RT1025-1AP04-ZW95 SIRIUS Power Contactor, S0, 3NO,","metaDescription":"Siemens SIRIUS 3RT1025-1AP04-ZW95 power contactor, size S0, 3 NO main contacts, 24 VDC coil, screw terminals, IP20 front, 140 mm depth.
