The screw-type terminals on the main circuit accept 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or up to 2x (0.75...4 mm²) solid conductors, and 2x (1...2.5 mm²), 2x (2.5...6 mm²), or up to 2x 10 mm² stranded — common panel wire sizes for this current class. Rated motor power reaches 11 kW at both 500 V and 690 V, and the AC-4 switching current at 400 V is 15.5 A — the rating that governs reversing or inching duty where the contactor makes and breaks stalled-rotor current. For straight motor starting (AC-3), the contactor is sized for the same 11 kW frame, so it handles pumps, fans, and compressors up to that load at line voltages from 400 V up to 690 V. Mounts via screw or snap-on onto 35 mm standard DIN rail per DIN EN 50022 — the S0 footprint is 45 mm wide, 85 mm tall, and 91 mm deep, so it occupies a single 45 mm module on the rail. ## Coil and auxiliary ratings The contactor coil is rated for 50 Hz operation with an operating range of 0.8 to 1.1 times the rated voltage at 50 Hz. The rated control supply voltage is 110 V at 50 Hz. Switching capacity for auxiliary contacts: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these cover typical PLC output or relay interface levels.","metaTitle":"Siemens 3RT1026-1AF00-ZX95 SIRIUS Power Contactor, 11 kW at","metaDescription":"Siemens SIRIUS 3RT1026-1AF00-ZX95 power contactor, size S0, 3 NO main contacts, 11 kW at 500/690 V, AC-4 15.5 A at 400 V, screw terminals, IP20 front, -25 to +60 °C.
