Application Value
  • Voltage-powered Type: More suitable for branches and boundary points with high importance and high fault rate:
    • Solve the blind adjustment problem of conventional fuses: ON/OFF position, voltage, current, power, etc.
    • Fault location: phase-to-phase short-circuit alarm, single-phase earth fault alarm, improve power supply reliability.
  • Current-powered Type: More suitable for user boundary points with small capacity, realizing intellectualization at low cost:
    • Solve the blind adjustment problem of conventional fuses: ON/OFF position, current
    • Fault location: phase-to-phase short-circuit alarm, improve power supply reliability.
  • Electrically Controlled Operation Type:
    • Local switching operation: eliminate potential safety hazards caused by manual closing to fault points
    • Remote switching operation: simplify operation process and reduce manual operation.
