CD4 series motor control protectorDetailed product description：

Mainly used for the protection and control of motors with rated operating voltage up to 690V and rated current ranging from 1.25 to 450A.
It has multiple control functions: direct start, Y/△ step-down start, resistance step-down start, autotransformer step-down start, reversible commutation start, and dual speed start
Communication function, using Modbus RTU communication protocol
Startup, control, and protection are integrated into the CPU, and communication between the field layer and control layer uses bus technology

The CD4 series motor control protector has overload protection, underload protection, locked rotor protection, unbalanced protection, phase failure protection, thermistor PTC protection, hourly starting frequency protection, external fault protection, ground fault protection or residual current protection, low voltage protection, overvoltage protection, underpower protection, and reverse sequence protection
The tripping levels of overload protection are divided into 10A, 10, 15, 20, 25, and 30, which can greatly optimize the use of electric motors
Built in CPU monitors the real-time status of the motor operation
Equipped with nine switch inputs and four relay outputs
Control protector complies with GB 14048.4 standard
The control protector has obtained the national mandatory product certification "CCC" mark
