Air Circuit Breaker Diagram. In addition the circuit breaker can be used as an across the line starter for large low. It dampens the arcing in case of overloading.
The working of vacuum circuit breakers is briefly explained below. Air circuit breakers generally have two pairs of contacts. Its primary function is to interrupt current flow after a fault is detected.
Making a drawing of the connections to all the component parts in the circuit s load makes it easier to understand how circuit components are connected.
Such breakers are used for low voltages generally up to 15kv and rupturing capacities of 500mva. Air circuit breakers generally have two pairs of contacts. It opens or closes a circuit automatically or manually. The following fig shows the main and outer parts of the acb.
