u Overview
• BR10-PR series reclosers are installed on MV overhead distribution lines in combination with a R-10 series recloser control. Recloser control monitors the status of distribution line by measuring the output of voltage and current sensors built into the recloser, and it performs the operation of the set protective elements according to the settings when a fault occurs.

u Key Features
• Main contact can be open and closed electrically or manually
• Position indicator to indicate the position of the main contact
• Manual tripping lever to manually trip the recloser
• Single control cable connection with its control
• Additional auxiliary contacts for the position of main contact
• Optional manual closing lever to manually close the recloser
• Mounting brackets for installation on poles or frame structures
• Vacuum interrupter and pole assembly encapsulated with HCEP(Hydrophobic Cycloaliphatic Epoxy) to provide outstanding insulation performance even in harsh outdoor environments
u Applications
• Used as a traditional protective device to protect distribution lines or substations
• Used as a protective device in systems requiring the automatic loop control scheme as well as line protective elements
• Used as a protective device in systems requiring the load shedding function to maintain constant power quality
• Used as a protective device for distributed energy resources connected to distribution lines
• Used as a circuit breaker to implement an automatic source transfer function to minimize outage durations for critical loads or customers
