Screw terminals on both main and auxiliary circuits: main accepts 2x (0.5–1.5 mm²) solid or 2x (1–2.5 mm²) stranded, up to 2x 10 mm² max; auxiliary takes 2x (0.5–1.5 mm²) solid or 2x (0.75–2.5 mm²) stranded, max 2x 4 mm². Front face is IP20; the terminal area is IP00 — keep live parts behind the gland plate. ## Motor duty and ratings Rated for 11 kW at 400 V AC-3 (standard squirrel-cage motor switching) and 11 kW at 500 V and 690 V — same power across the higher voltage range. AC-4 (plugging/reversing/inching) rating is 15.5 A at 400 V. AC-2 (slip-ring motor) also carries 11 kW at 400 V. For resistive loads (AC-12) the contactor handles 10 A. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V DC. Mechanical life is 10 million cycles typical.","metaTitle":"Siemens 3RT1026-1AC00 SIRIUS Power Contactor, 3NO, 11 kW at","metaDescription":"Siemens SIRIUS 3RT1026-1AC00 power contactor, size S0, 3-pole NO, 11 kW at 400 V AC-3.
