The BE1-851E is an enhanced overcurrent protection system based on the design of
the BE1-851, a multifunction, numeric relay that provides three phase, ground, and
negative sequence overcurrent protection with four shot recloser, breaker failure,
breaker monitoring, control, and metering functions in an integrated system.
• Includes two additional Control Outputs as compared to the BE1-851.
• Allows the user to select the optimal response characteristic separately for phase
and ground elements. Choose between fundamental, RMS, or average sensing
algorithms.
• BESTlogic provides the user with complete flexibility in configuring a protection
and control system. User programmable variable and switch names make these
relays completely self documenting.
• Programmable LCD display allows the relay to replace local indication and control
functions, such as panel metering, alarm annunciation, and control switches.
• Three independent communication ports with protocol support allows integration
with distributed control systems.
• Real Time Clock with 8 hour capacitor ride through and optional battery backup.
• Available in a fully drawout case configuration.
