What's the functions of KPM60 motor protector

Release time：2019-01-14 ~~Times of browsing：~~

KPM60 series smart motor protector is suitable for rated voltage 380V to 660V rated current 5A-500A control loop. It has 19 basic protection functions, which could better realize the motor protection and data monitoring.

Because the usage, performance, environment of motors are different, Compere Smart developed this KPM60 smart motor protector in order to avoid user’s inconvenience in protector selection and the extra cost of buying the unnecessary function.

KPM60 motor protector function selection

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:
