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.
