The purpose of the Y-Δ (star-delta) control box water pump control box is to reduce the starting current and reduce the damage to the power grid and common equipment.
The condition that the star-delta start is required is that when the load is light, the load is heavy when starting, the load has no strict requirements on the starting torque of the motor, and the starting current of the motor is limited. The motor meets the 380V/Δ wiring condition to adopt the star-delta starting method.

The method is: when the motor starts, the motor is connected to the star type wiring, and when the motor starts successfully, the motor is changed into a triangle type wiring.
Since the motor starting current is proportional to the power supply voltage, the starting current provided by the grid is only 1/3 of the full voltage starting current, but the starting torque is only 1/3 of the full voltage starting torque.
The star-delta startup, which is a buck start, is achieved at the expense of power in exchange for lowering the startup current.

The star-delta start-up circuit reduces the starting current and reduces the damage to the grid and common equipment.
Low manufacturing cost and long service life, but the starting torque is fixed at 1/3.

The star-delta start control box has overload, short circuit, phase loss protection and pump body leakage.
Motor over temperature and leakage and other protection functions and complete status display, with single pump and multi-pump control mode, a variety of active and standby pump switching methods and various starting methods.
