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.
