EC670/650 intelligent microcomputer protection device can be used as a variety of substation wiring methods

Control, monitoring and protection devices for circuit breakers, isolating switches and ground switches.

These two devices, both based on IEC 61850 standards, have a wide range of applications

Sex. The design of the REC670/650 reflects the core values of the 61850 standard, thus ensuring that

Maintain an open, flexible and future-proof system architecture with the most current

Advanced performance. Therefore, the REC670/650 series device is the old station upgrade and new

Ideal for building substation applications.
