Product Positioning

The 3RA2434-8XF32-1AL2 is a star-delta contactor combination of size S2 in the SIRIUS 3RA24 series, suitable for three-phase motors of 22 to 30kW, providing stable reduced-voltage starting performance under AC-3 operating conditions.

Core Product Advantages and Features

Supports larger motor power

The S2 size design can handle the starting current of motors ranging from 22 to 30 kW.

Electrical and mechanical double interlock

Ensure that star and delta contactors do not conduct simultaneously, thus improving system safety.

230VAC control power supply

The coil is designed with 230 volt AC power, making it suitable for production lines that already have AC control power.

Screw terminals facilitate maintenance

Both the main and auxiliary circuits use screw terminals for easy inspection and replacement in the future.

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.

3RA24268XF321BB4

The star-delta starting assembly uses S0-size contactors and has a rated current of approximately 50A. It can handle the AC-3 starting requirements of a 22kW/400V motor and has a mechanical life of tens of millions of operating cycles, making it suitable for production lines with frequent start-stop operations.

3RA24268XF321AN2

Like the 3RA2426 series, it belongs to the S0 size star-delta contactor combination and can carry the AC-3 starting current of a 22kW/400V motor. The main circuit contact configuration and terminal type are designed in accordance with the standard specifications of the same family.
