KPM60F Low-voltage Motor Protection Controller
The KPM60F split-type motor protection controller is suitable for industrial applications to protect motors. It significantly simplifies the secondary control and protection circuits of the motor by providing protection, control, measurement, and fault management functions. It offers comprehensive protection and control measures, and its network-based communication with various buses enables networked management of the motor.
KPM60F adopts a modular design, which is small and compact, and easy to install. It can be used in low-voltage control terminal cabinets and 1/2 module or larger drawer cabinets for DIN rail installation, and is suitable for applications in coal mines, petrochemical plants, metallurgy, and power industries.
