JJ1 series auto-voltage reducing starting control cabinet is suitable for three-phase squirrel-cage induction motor of AC 50Hz, rated
voltage up to 660V and below, and the capacity 315kW and below, used for infrequent auto step-down starting to reduce the impact from
the motor starting current on the power transmission network, and to help the motor accelerate to the rated speed and stop the motor
by hand. It can protect the motor against the over load, phase failure, short circuit, etc.. The auto transformer is mounted with starting
overload protection device.

 Structure

 JJ1 series auto voltage reducing starting cabinet is designed into the cubicle type protection structure, made up of
auto transformer, circuit breaker, AC contactor, thermal relay, current-time converter, current-voltage meter. There are three
working ways that is the manual control, automatic control and remote control, hereinto, the manual control and automatic
control are performed by transfer switch, and the remote control is performed by the remote-control input connection terminal.
        The auto transformer have two sets of taps of rated voltage up to 80% and 65%. And when the product leaves factory,
 it is connected to the tap of rated voltage up to 65%. The product is also connected to the tap of rated voltage up to 80%
according to customers' requirements. In addition, user can indicate the tap connection position while placing an order.
