The 24 VDC coil draws its holding current from a standard control supply; verify the free-wheel diode polarity if the coil is driven by a PLC output. The 45 mm width and 85 mm height fit standard S0 panel layouts. Side-by-side mounting is permitted with zero lateral clearance, so no gap is needed between contactors on the rail. Screw-type terminals on the main circuit accept 2x (1... 2.5 mm²) stranded or 2x (2.5... 6 mm²) solid, up to 2x 10 mm² maximum. Auxiliary terminals handle 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²). The IP20 front-of-terminal protection means the contactor is safe for finger contact in a live panel; the terminal body itself is IP00, so it relies on the enclosure for environmental sealing. ## Duty ratings and motor switching The 11 kW rating at 400 V for AC-2 covers slip-ring motor starting where the contactor opens under load. The AC-4 rating of 15.5 A at 400 V is the limiting figure for reversing or inching duty — if your application requires frequent plugging, size the contactor on this number, not the AC-3 power. Auxiliary contact ratings cover the typical control-voltage range: 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V DC. The mechanical endurance of 10 million operations means the contactor outlasts most panel designs under normal switching frequencies. The rated insulation voltage is 400 V at 50 Hz, with an operating altitude limit of 2000 m and ambient temperature range of -25 to +60 °C.","metaTitle":"Siemens 3RT1026-1AV00-1AA0 SIRIUS Power Contactor, 11 kW AC-","metaDescription":"Siemens SIRIUS 3RT1026-1AV00-1AA0 power contactor, size S0, 3-pole, 11 kW at 400 V AC-2/AC-3.
