Rated for 11 kW at 400 V AC-2 (standard motor switching) and 15.5 A at 400 V AC-4 (reversing or inching duty) — the AC-4 number is the one that governs if you're jogging or plugging a load; the AC-2 figure covers normal start/run. With type 2 coordination, a 35 A gL/gG fuse protects the contactor and downstream wiring; type 1 coordination allows a 100 A fuse — the type 2 figure is what most panel builders spec for a coordinated starter. ## Terminal and wiring notes Main circuit terminals accept 2x (0.25–2.5 mm²) solid or 2x (1–2.5 mm²) / 2x (2.5–6 mm²) stranded, with a maximum 2x 10 mm² — AWG equivalents 2x (16–12) solid, 2x (14–10) stranded, or 1x 8. Depth is 140 mm — that's the dimension from the DIN rail face to the back of the terminals, so check your enclosure depth if you're swapping into a shallow gland box. Side-by-side mounting is allowed with zero clearance, which keeps the rail fill factor tight.","metaTitle":"Siemens 3RT1026-3AF04-ZX95 SIRIUS Power Contactor, 3-Pole, 1","metaDescription":"Siemens 3RT1026-3AF04-ZX95 SIRIUS power contactor, S0 frame, 3 NO main contacts, screw terminals, 45 mm width, 11 kW at 400V AC-2.
