Medium voltage electronic sectionalizers AutoLink

Save time, effort and money!

The ABB AutoLink sectionalizer is an isolating device that automatically isolates the faulted section of the overhead network when a permanent fault occurs. If a temporary fault occurs, the AutoLink allows the upstream recloser or breaker to clear the fault without interrupting the circuit. Both AutoLink electronic sectionalizer and the wireless version of Autolink, WiAutoLink, are designed to improve reliability and service continuity.
