Product Description
Product Overview
3 phase overload control motor overcurrent & short circuit protection relay
KPM60 series motor overcurrent & short circuit protection relay is suitable for control protection circuit that rated voltage 380V to 660V, rated current 5A to 500A , providing a sound protection and control measures, It could achieve motor network management by the communication method that based on a variety of bus, the controller application greatly improves the design and production efficiency, reducing the on-site commissioning and maintenance workload.
As a motor protection component, the motor protector effectively guarantees the safe operation of the motor, replaces the thermal relay, and realizes the motor control automation by using advanced communication technology.
