Basler BE1-700C - User Manual

BE1-700C
Digital Overcurrent
Protective Relay
The BE1-700C is a compact multifunction, numeric relay that
provides three phase, ground, and negative sequence overcurrent
protection with breaker failure, breaker monitoring, control, and
metering functions in an integrated system. Four shot reclosing
is available as an option. An onboard Ethernet option can provide
Modbus/TCP connectivity or can provide web and email
capabilities.

ADVANTAGES
• All of the advantages of a fully numeric
product in an economical “current only”
protection package.
• Compact design requires minimal panel
space for overcurrent and reclosing
applications.
• Adds Oscillography, Sequence of Events,
and Metering when single function current
relays are replaced with the BE1-700C.
• 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.
• Two independent communication ports
with protocol support allows integration
with distributed control systems.
• Available with or without reclosing.
• Optional BESTNet Ethernet package
provides metering and status web pages,
settings and configuration via Ethernet,
and email notification of user-defined
events.
