ZGLEDUN Series LDM9EL-125 Product Main Function:
◊ Long-delay, short-delay and instantaneous three-stage protection, using electronic tripping, has nothing to do with the power supply voltage.
◊ It has high breaking capacity to ensure the reliability of line short-circuit protection.
◊ Built-in electric operating mechanism to realize remote opening and closing.
◊ Overvoltage protection, undervoltage protection, phase loss protection.
◊ Real-time display of line residual current, three-phase power supply voltage, load current, power, and electricity.
◊ The protection functions and parameters can be set and modified online.
◊ The trip type (residual current, blocking, overload, undervoltage, overvoltage, phase loss) is identified and displayed, and can be stored, inquired, and deleted.
◊ With communication function, it can realize the push of alarm information of voltage, current, load, open circuit, leakage and other faults and abnormality of power lines.
◊ It can be connected to a variety of communication modules, 4G, WIFI, power broadband carrier (HPLC), Ethernet, etc.
◊ Integrated six chips
