Product Description

General:
FN5-12 series indoor AC HV load switch is suitable for AC 50Hz, 10kV network to break load current and close short-circuit current. The load switch with fuse can break short-circuit current as protection switch. This series is fitted with specialized CS manual operating mechanism or CS6-1 manual operating mechanism.

Characteristics:

1. Small dimension, light weight, simple structure, convenient maintenance, small operating force.

2. Reliable mechanical interlock prevents mal-operation

3. Clearly visible opening

4. Applied self-energy gas-generation arc-extinguishing has stable performance. It is both safe and reliable.

5. Composite equipments have open-phase protection function.
