high voltage disconnect BHA 10kV circuit breaker Load break switch BHA-10 630A with fuse
The BHA load break switch is used to cut off the current during repair or maintenance work. The switch-disconnector has arcing chambers, this allows the current-carrying knives to be opened without damage, which can be caused by the arc arising in this case.
Load break switches are used for switching on and off under load three-phase electrical circuits with voltage up to 10 kV, current up to 630A. The switch disconnector, like the disconnector, provides a visible open circuit, however, during operations under load, an electric arc forms between the contacts. To combat this effect, the circuit breakers are equipped with special arcing chambers made of polymethyl methacrylate, which has the ability to emit gas that effectively extinguishes the arc.
