Automatic Circuit Recloser (ACR) is an intellectual protective device capable of interrupting fault current and which purpose is to increase distribution system reliability. Their function is to automatically disconnect a section of feeder in the event of fault, such as a short circuit. After a certain period of time, the recloser makes a specified number of attempts to re-energize the line to restore power supply to consumers.

Main Functions of Reclosers
Recloser can be used both to perform simple protective functions and complex algorithms for automation of distribution networks. Modern reclosers perform the following functions:

Automatic disconnection of damaged line sections;
Auto-reclosing;
Automatic restore of power supply from the network of alternative power source
local and remote network reconfiguration;
Self-diagnostics;
Measurement of network mode parameters;
Keeping the logs of operational and emergency events in the line;
Remote control.
