For heavy-duty jogging or inching applications, the AC-4 rating is 15.5 A at 400 V — that is the current it can break reliably during frequent starts and reversals. The AC-2 rating of 11 kW at 400 V covers wound-rotor motor switching, where the contactor must handle slip-ring currents without welding. Main circuit connections are screw-type terminals accepting up to 2x 10 mm² or 1x 8 AWG, with a separate solid/stranded capacity of 2x (0.5...1.5 mm²) through 2x (0.75...4 mm²) for the coil and auxiliary wiring. Operating altitude is rated to 2 000 m without derating. Coil operating range spans 0.8...1.1 × rated voltage at both 50 Hz and 60 Hz, with rated coil voltages of 110 V at 50 Hz and 120 V at 60 Hz. The auxiliary contact block includes 2 normally open instantaneous contacts, rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for direct PLC input or small relay loads.","metaTitle":"Siemens 3RT1026-1AK64-3MA0 SIRIUS Power Contactor, 11 kW at","metaDescription":"Siemens SIRIUS 3RT1026-1AK64-3MA0 power contactor, S0 frame, 11 kW at 690 V AC-3, 15.5 A AC-4, screw terminals, DIN rail mount, current production.
