GDH-KT series motor protector

GDH-KT series motor protectorIt is a comprehensive motor protector produced by our company using advanced electronic circuits and brick technology,Compared to similar domestic products that use ordinary circuits,Technically, it has already reached a higher level.This product has symmetrical faults(Such as overload, locked rotor, overvoltage, undervoltage, etc)And asymmetric faults(Such as phase failure and current imbalance)The protection function,When used in conjunction with AC contactors, it can provide fast and reliable protection for any type of three-phase motor.It is mainly suitable for industrial three-phase motors and three-phase power feeding systems in metallurgy, chemical industry, textile, building materials, power, communication, etc.Easy to use this machineRS485Communication interface andPCNetwork systems composed of devices such as machines or through4-20mAOutput andDCSSystem connection.GDH-KT series motor protectorHas a simple structure, reliable action, high accuracy, and strong anti-interference ability,Stable work performance,Advantages such as simplicity and ease of operation
main features:
1The current sampling method of the main circuit passing through the protector current sensor.
2The current value is displayed digitally, and the fault cause indicator light is displayed.
3Overcurrent protection with inverse time limit.
4The rated current and starting delay time can be set separately.
5Compact structure, can be combined into one or installed separately.
6Having4-20mAStandard current signal output, can be directly connected to industrial secondary instruments or computer systems.
7One machine with multiple uses,Can replace ammeters, thermal relays, current transformers, time relays, and leakage devices, etc.
8HavingRS485interface,Can achieve information transmission,One upper computer(PC)Can be connected256Taiwan protector,And can set parameters for each motor,Start stop operation,Easy to automate management.
