A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then has to be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

Air circuit breakers are most commonly found in large industrial facilities. They are typically controlled electronically. An important characteristic of air circuit breakers is that they are almost always set up to facilitate easy maintenance.
The ease of access for maintenance purposes is important, especially if your air circuit breakers control the electrical supply for a large facility or hospital. If something goes wrong with one of the circuit breakers, you want your maintenance personnel to be able to quickly identify the problem and get to the parts they need to reach to fix it.
Air circuit breakers are made for this sort of ease of access, making them a desirable choice for large-scale business operations.
