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.
- Non-enclosed switch for extra safety
- Integrated air break switch for personal safety
- Operation On and Off with full load without electric power
- Follows the feeding substations reclosing sequence
- Easy installation
- Frame of "Marine grade" premium stainless steel
