Circuit Breaker

Features

Even in the event of complete gas leak, our SF6 CBs are capable of breaking 100% normal current & with stand system voltage

Advance warning of gas leak by continuous preassure monitoring.

Explosion proof and FAIL - SAFE CB by means of saftey membrane for each pole.

Inbuilt interlocks for prevention of withdrawing / Insertion of closed CB. Operation of CB is possible only in Test, Service or Isolated position.

Automatic Safety shutters to cover live parts when CB is withdrawn.

No degradation of main current carrying contacts, as there are seprate current carring and arcing contacts.

Our SF6 CBs operate at low preassure. The internal preassure rise at the instant of current interruptionalso stays low. Due to this and the high dgree of gas tightness adequate for entire life of the breaker os ensured.

Operating Mechanism

Proven Spring operated Mechanism.

Designed to closed and latch.

Manual / Motorised Option.

In built trip free mechnism.

In built anti pumping feature.

Mechanical ON/OFF indication.
