The AC-4 rating (15.5 A at 400 V) governs plugging and inching cycles; if your application requires frequent reversing, this is the limiting figure. For AC-1 resistive loads the contactor can carry 10 A at 24 V, 6 A at 230 V, 3 A at 400 V. The 60 Hz coil (0.8–1.1 A at 220 V) is fixed — no 50/60 Hz dual-frequency coil here, so verify supply frequency. Type 1 coordination requires a 100 A gL/gG fuse; Type 2 coordination needs 35 A gL/gG. That means the contactor can clear a fault up to 100 A without damage to the enclosure (Type 1) or with limited damage (Type 2). Width 45 mm, height 85 mm, depth 91 mm — fits a standard S0 footprint on 35 mm DIN rail. Side-by-side mounting allowed (no derating gap required). Main circuit terminals accept 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²) solid/stranded; auxiliary terminals accept 2x (1–2.5 mm²) or 2x (2.5–6 mm²), max 2x 10 mm². AWG equivalents: main 2x (16–12), 2x (14–10), 1x 8; auxiliary 2x (20–16), 2x (18–14), 1x 12.","metaTitle":"Siemens 3RT1026-1AN10 SIRIUS Power Contactor, S0, 11 kW AC-2","metaDescription":"Siemens SIRIUS 3RT1026-1AN10 power contactor, size S0, 3 NO main contacts, 11 kW at 400 V AC-2.
