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.
