What is Air Break Circuit Breaker? | Its Advantages & Disadvantages

Are you What is Air Break Circuit Breaker? | Its Advantages & Disadvantages?. If yes then I am sharing detailed information about Air Break Circuit Breaker? in this post.

What is Air Break Circuit Breaker?

The low voltage Air Break Circuit Breaker shown in the figure is designed for dissipation capacity up to 15 kV.Voltage. They are used in both types of voltages. Its movable and immovable contacts are usually made of copper or silver metal. These are called primary contacts (CC) Horn shaped arcane contacts are often made of carbon alloy, which propels the arc produced in the circuit baker‘s operating state (towards the horn ends). As a result, the arc is connected to the blowout system. The coil of a blowout system generates a powerful magnetic field, which causes the arc to wither. Due to the strong magnetic field, the arc is pulled upwards, and the length of the arc increases. Hence the arc ends.

Advantages of Air Break Circuit Breaker

  1. Their installation and testing are easy
  2. Their installation is straightforward.
  3. Along with manual operation, they can also be self-propelled.
  4. They do not require oil.
  5. Their structure is straightforward.
  6. Their operation is effortless.
  7. They look neat and beautiful.
  8. Their maintenance cost is low.
  9. The cost of their installation is more minor.
  10. Due to the connection and opening of contacts in the air medium can be operated repeatedly, so they are used more in factories.
  11. The short circuit current can be easily reduced because the short circuit current depends on the arc resistance.

Disadvantages of Air Break Circuit Breaker

  1. These circuit breakers are often required to be used in a closed position.
  2. They are often designed for small voltages.
