SEL-351R Falcon™ Recloser Control
Take Control of Your Recloser
Major Features and Benefits
The SEL-351R Falcon Recloser Control provides microprocessor-based features in a slim-profile housing for
long, reliable service on your distribution system.
➤
Modernize existing recloser installations to provide cost saving protection, automation, and
control features. Single-person-lift size and standard control cable interconnection simplifies
installation. Available in Lift-To-Open and Swing-Open enclosure options.
➤
Use automatic network reconfiguration for improved reliability. Patented M
cations speeds protection and improves security.
➤
Customize controls by using enhanced SEL
Configurable front-panel control labels simplify custom functions.
➤
Improve feeder loading by using built-in, high-accuracy metering functions. Use watt and var measure-
ments to optimize feeder operation. Measure three-phase values with either three potential transform-
ers or use "phantom" values derived from a single-phase voltage.
➤
Increase efficiency of service restoration with accurate fault location when connected with three-phase voltages.
➤
Reduce engineering costs with
gramming. The built-in HMI provides phasor diagrams that help support commissioning and troubleshooting.
➤
Power with 120 Vac or 230 Vac (or 125 Vdc or 250 Vdc).
