Load Break Interrupter 12kv 200A Vacuum Load Break Switch 80KA
Overview of Load Break Interrupter 12kv 200A Vacuum Load Break Switch 80KA
FN16A-12 Series Indoor AC HV Vacuum Load Switch is suitable for
50Hz, 10kV rated voltage alternative current
power net, for breaking load current, overload current and
combination apparatus or for breaking short circuit
current and opening and closing short circuit current. It is widely
used in places of no oil reaction, free of
maintenance and frequent operations situation. With advantages of a
newly design, small volume, flexible
installation, simple and easy to operate, this kind of product has
manual operation and motor drive functions.
And the operation mechanism is CS6-1 type or specified CS type, it
could be operated in the back of the switch
without any operation mechanism attached.
Characteristics of Load Break Interrupter 12kv 200A Vacuum Load Break Switch 80KA
1. All-assembled switch and combined equipment has small dimension
and compact structure
2. Both manual and electric operating mechanism with small
operating force
3. Reliable mechanical interlock prevents mal-operation
4. Clearly visible clearance
5. Apply air compression arc extinguishing with stable performance
and reliable, safe operation
6. The combined electric equipment has open-phase protection
function
