The VBF breakers are designed per the latest IEC standards.
Vacuum Circuit Breakers VBF are designed for distribution systems rated at 36 kV and are of live tank design. The vacuum interrupters are housed in hollow porcelain insulators filled with SF6/Nitrogen gas at 0.5 bar above atmospheric pressure to safeguard against condensation. A spring operated mechanism is housed in a weather-proof cabinet and a sturdy extruded steel angle structure is used for mounting the breaker.
