The main circuit uses screw-type terminals accepting 2x (1 to 2.5 mm²) solid or 2x (2.5 to 6 mm²) stranded, up to 2x 10 mm² maximum. Two built-in auxiliary contacts (1 NO + 1 NC) handle control logic at 24 V (10 A), 230 V (6 A), or 400 V (3 A), covering typical PLC output and pilot-device interfacing. At 85 mm high and 140 mm deep, the S0 frame fits standard distribution board gutters and leaves room for wiring ducts above and below. Pollution degree 3 rating suits the conductive-dust and humidity conditions typical of factory-floor enclosures. The contactor's mechanical endurance is 10 million cycles typical, so it holds up in high-duty cycling applications like conveyor sorting or pump sequencing. Type 1 coordination (contactor may need replacement) allows a 100 A fuse. These values directly affect the upstream protective device selection in the panel schedule.","metaTitle":"Siemens 3RT1026-1AR64 SIRIUS Power Contactor, S0, 11 kW at 4","metaDescription":"Siemens SIRIUS 3RT1026-1AR64 power contactor, size S0, 11 kW at 400 V AC-2, 45 mm wide, screw terminals, current production.
