QX4 Star Delta Starter Control Panel Wall Mounted Vertical Type IP65

QX4 Series Vertical Type Wall-Mounted Star-Delta Starting Cabinet

Main functions and features

When the starting cabinet starts up the motor,the voltage being applied to stat or winding of each phase is reduced to 57. 7% of voltage in circuit,and the current is 1/3 of direct starting value, meanwhile, the starting torque is reduced to 1/3 of direct starting value. Working system of starting cabinet is interrupted continuous duty system or repetitious short-time duty system, operating frequency under repetitious short-time duty system is 30 times per hour,interval time of interrupted continuous duty system is 90s.

Main Technical data

Application

QX4 series star-delta starting cabinet is applicable to three-phase squirrel cage motor of AC50HZ/380V with power up to 135KW,used for controlling the starting, running and stopping of switching from "star" to "delta"of motor stat or winding, protects the motor against overload or open-phase.
