REB670 - Busbar protection

State-of-the-art protection - for your equipment and your people

The REB670 IED (Intelligent Electronic Device) is designed for the protection and monitoring of busbars, T-connections and meshed corners from medium to extra high voltage levels. Due to its extensive I/O capability, REB670 protects single and double busbars with or without transfer bus, double circuit breaker or one-and-half circuit breaker arrangements.

It provides selective, reliable and fast fault clearance for all types of internal phase-to-phase and phase-to-earth faults in solidly earthed or low-impedance earthed power systems. It can also handle all internal multi-phase faults in isolated or high-impedance earthed power systems.
