Autoself,
time-voltage
sectionalizers

Autoself(TM) Time Voltage Sectionalizer TVS is built of the OVX’s high performance outdoor vacuum circuit breaker module and high speed TVX electronic sectionalizer module. The AutoSelf functionality is built on a auto-reclosing cycle count, lockout function and simple time‐voltage logic including multiple timers. It can be operated manually via push buttons and a rotate switch.
