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

control equations for improved system operation.

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
