VCB Panel (Vacuum Circuit Breaker - HT Panel)

Leveraging the skills of our qualified team of professionals, we are instrumental in offering a wide range of HT Vacuum Circuit Breaker Panel to all over the world upto 33kV.

A vacuum circuit breaker is a kind of circuit breaker where the arc quenching takes place in vacuum The operation of switching on and closing of current carrying contacts and interrelated arc interruption takes place in a vacuum chamber in the breaker which is called vacuum interrupter.

Vacuum Circuit Breaker is renowned technology today and is also known as the most reliable current interruption technology for medium voltage switchgears.

ADVANTAGES OF VACUUM CIRCUIT BREAKER PANEL

  • The vacuum circuit breaker has a long life. Unlike Oil Circuit Breaker (OCB) or air blast Circuit Breaker (ABCB), the explosion of VCB is avoided.
  • This enhances the safety of the operating personnel. No fire hazard.
  • The vacuum CB is fast in operation so ideal for fault clearing.
  • VCB is suitable for repeated operation.
  • Vacuum circuit breakers are almost maintenance free.
  • No exhaust of gas to the atmosphere and Noiseless operation.
  • Vacuum circuit breaker does not require any additional filling of oil or gas.
  • Rapid recovery of high dielectric strength on current interruptions that only a half cycle or less arcing occurs after proper contact separation.

SAFETY INTERLOCKS

  • Interlocks are provided such that the breaker closing is prevented in intermediate position between service and test/isolated positions
  • Mechanical interlocks to prevent truck racking in /out when breaker is in closed position.
  • Breaker can be inserted only when control plug & socket in position(Optional)
  • Mechanical castle key interlock with upstream /downstream isolators can be provided on request.
