HIGH-SPEED, PEER-TO-PEER PROTOCOL	Enables transfer to an alternate source in as little as six cycles ensuring minimal service disruption PeerComm protocol enables the two reclosers to maintain constant communication
FLEXIBLE, USER-SELECTABLE RESTORATION OPTIONS	Helps utilties quickly return systems back to the normal states after the return of the primary voltage source Local restoration enables each control to be manually operated Automatic restoration / Manual initiation enables restoration to the preferred source to be manually initiated from either control Automatic restoration / Automatic initiation enables retoration to occur once the preferred feeder voltage returns
MINIMIZED VOLTAGE SENSING REQUIREMENTS	Only source-side voltage sensing is required for each recloser Eliminates redundant measurements and unnecessary data
FAST TRANSFER TIMES	Allows source transfer to occur before backup power is required, including generators
