Air Circuit Breakers Have Many Uses
It should be noted at the outset that you will not find air circuit breakers inside every panel or in many applications. These somewhat unique devices have particular specifications and uses. It should also be noted that you cannot change one type of device for another without consultation with an expert. What this means in practical terms is that you cannot switch out air circuit breakers with other types (such as vacuum or non-air,) without first getting approval from a reputable source.
Air Circuit Breakers Rated Up to 10,000 AMPs
Air circuit breakers can be rated up to 10,000 amps. They may also have particular trip characteristics, which can often be fully adjustable. This can include configurable trip thresholds and delays.
Air Circuit Breakers Used for Main Power Distribution in Large Plants
For the most part, air circuit breakers are electronically controlled, but this is not always the case. There are some units of air circuit breakers that controlled through microprocessors via an integral electronic trip unit. While there is certainly the possibility of various types of uses for air circuit breakers, they are often used for main power distribution in large industrial plants. One of the many important reasons they are often used in these applications is because the air circuit breakers can be set up or arranged in draw-out enclosures, for ease of maintenance and improved worker safety.
Switching Out Air Circuit Breakers Requires Licensed Personnel
The actual, individual mechanics of how the devices work are determined by the manufacturer and their design team. This is an important aspect when you are looking to replace your devices. It is important that you investigate the inside of the panel in order to learn the exact model and type of device that you need. You should never attempt to switch out one type of device with another type or brand of device, without first checking compatibility issues. Switching out these types of devices should be done with extreme care and should be conducted by licensed personnel.
In general, there are two methods used to make the devices work when a fault is detected. One method will use compressed air to blow out the arc, or the other method is that the internal contacts swing very rapidly inside the small, sealed chamber, which allows the displaced oxygen to escape, thus blowing out the arc.
Old Parts of Air Circuit Breakers Can Be Replaced with New Parts
It is good to note that these devices can often be remanufactured, which is a good way to save money on these devices. In essence, the old parts of the air circuit breakers are replaced with new parts. This is basically a rebuilding procedure of the air circuit breakers.
