Siemens 3RT2024-1AK60 Industrial Power Contactor

The Siemens 3RT2024-1AK60 is a 3-pole Sirius power contactor designed for AC-3e/AC-3 duty, rated to switch up to 12 A and deliver 5.5 kW at 400 V in motor-control applications. It features a 3-pole main circuit and an integrated 1 NO + 1 NC auxiliary contact, with screw-terminal connections and a compact S0 size suitable for panel mounting. The coil voltage options are 110 V AC (50/60 Hz) or 120 V AC (60 Hz), enabling compatibility with common control circuits while maintaining reliable pull-in characteristics. With a net weight around 0.403 kg, this device is part of Siemens’ SIRIUS 3RT family of power contactors, designed for motors up to 250 kW (per the family range) and known for long mechanical life. Additional electrical ratings include insulation voltage up to 690 V and surge-voltage resistance around 6 kV for both the main and auxiliary circuits, supporting robust operation in challenging industrial environments. The contactor is rated for operation from -25 to +60 C and up to 2,000 meters above sea level, making it suitable for a variety of installation sites in manufacturing and processing lines, conveyors, pumps, and other motor-driven equipment. This 3RT2024-1AK60 provides a reliable, compact solution for controlling three-phase motors with straightforward screw-terminal wiring and built-in auxiliary signaling, helping simplify control logic while delivering proven Siemens quality.
