What's the functions of KPM60 motor protector
Release time：2019-01-14 Times of browsing：
Through a lot of on-site and user research, we add the higher frequency and widely used function into standard selection. And those low frequency and not widely used functions are added to the optional function. In this way, which avoids extra cost of unnecessary functions.
For example, KPM60 series low voltage motor protector supports the Modbus-RTU and Profibus-DP communication. However, Profibus-DP communication has a small audience and a narrow application field. If the communication is added to the standard configuration, it does not make any sense to the user. Modbus-RTU communication is the popular mainstream communication method. Adding it in the standard configuration, can help users effectively realize the communication of the motor protector.
The following figure shows the KPM60 standard function configuration table:
