SONTUOEC series Distribution box Star-delta control box for water pump
Star-delta control box for water pump control box 12 months warranty period ISO certified China quality Distribution box
Star-delta control box water pump control box product description
Star-delta control box for water pump control box 12 months warranty period ISO certified China quality Distribution box
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.

Star-delta control box Features
Star-delta control box for water pump control box 12 months warranty period ISO certified China quality Distribution box
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.
