Both are standard fuse classes available from any electrical wholesaler. The S0 frame size keeps the footprint compact at 65 mm wide × 85 mm tall × 91 mm deep. Main current circuit uses screw-type terminals accepting 2x (0.25–2.5 mm²) solid, 2x (1–2.5 mm²) or 2x (2.5–6 mm²) stranded, and up to 2x 10 mm². AWG equivalents are 2x (16–12) solid, 2x (14–10) stranded, and 1x 8. Auxiliary contacts: 2 instantaneous, rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC. The auxiliary contact ratings cover typical PLC-level signal switching and control relay loads.","metaTitle":"Siemens 3RT1026-3AG16 SIRIUS Power Contactor, S0, 11 kW at 4","metaDescription":"Siemens 3RT1026-3AG16 SIRIUS S0 power contactor, 11 kW at 400 V AC-2, 15.5 A AC-4, screw terminals, IP20 front, current production.
