Siemens 3RT2026-1AK60 Three Phase AC Contactor

Siemens Sirius 3RT2026-1AK60 is a 3-pole power contactor designed for AC-3 motor control up to 11 kW at 400 V, delivering reliable direct-on-line switching for three-phase motors. It uses a 110 V AC coil compatible with control circuits at 50/60 Hz and includes an auxiliary contact pair (1 normally open and 1 normally closed) for auxiliary circuits or feedback signals. The device uses screw terminals, comes in size S0, and carries front IP20 protection. With a rated current of 25 A (AC-3), it is suitable for motor starters and similar load applications, and its insulation voltage is 690 V. The unit is rated for ambient temperatures from -25 °C to +60 °C and installation altitudes up to 2,000 m. Mechanical life is robust, typically documented up to 10,000,000 operating cycles, making it a durable choice for repeated start/stop duty in industrial control panels. This model is part of Siemens’ Sirius 3RT2 family, offering a compact, reliable solution for controlling three-phase motors with integrated auxiliary feedback for control logic.
