3RA24178XH311BB4
The star-delta starting combination, consisting of three S00-sized contactors, includes an electromechanical interlock mechanism to prevent the star and delta contactors from engaging simultaneously, making it suitable for the reduced-voltage starting requirements of small and medium-power three-phase motors.
Product Positioning
The 3RA2417 series star-delta contactor assembly is composed of S00 size contactors and has built-in electrical and mechanical double interlocks, providing a reduced-voltage starting solution for 11kW/400V class motors under AC-3 operating conditions.
Core Product Advantages and Features
Double interlock protection
It also features electrical and mechanical interlocks to prevent short circuits caused by malfunctions of star and delta contactors.
Compact S00 size
Its compact size makes it easy to install in control boxes with limited space.
24VDC control power supply
It adopts a 24-volt DC coil design, which is suitable for direct drive with PLC output.
Screw terminal wiring
Both the main circuit and the auxiliary circuit use screw terminals for easy on-site wiring and maintenance.
