Meaning of type

Technical descriptions
1.The protector adopts the advanced microprocessor which has functions of high precise data processing, advanced protection arithmatic,high protection precision
and responds quickly It has various functions of leakage latch, under-voltage,
over-voltage,three-phases imbalance, over load, short-circuit, wind and electricity latch,gas protection,etc.
2.Adopts 4*4 Chinese LED displayer with menu man-computer screen, can be operated simply and conveninently;when it works,displays plenty of information about the present three-phase current, system’s voltage and the operation status of switch.
3.All the parameter of protection functions could be adjusted through choosing the menu. It has wide application range and high precision.
4.Has good memory function, each protection funcion adjusted could be memorized and saved, when the power is on or the system is reset, parameter adjusted last time could be read, and protector could memorize the present malfunction information.
5.Software self-testing function, the system will display relevant fault information
when the problems occur.
6.Remote and close control functions could be operated through the pull position of button switch on the surface.
7.Data communication interface connects with controlling system can be chosen,also the communication interface can be equipped as per users’ communication agreement.
