What Are the Different Types of Eaton Breakers?


Eaton classified breakers generally fall under four different types, which are:

1. Molded Case Circuit Breakers (MCCBs)

MCCBs deviate from standard circuit breakers by merging current- and temperature-sensing features. With these characteristics, MCCBs, particularly those from Eaton, can help protect from issues like:

2. Low-Voltage Air Circuit Breakers

It’s important to note that MCCBs can also fall under the low-voltage circuit breaker type. These low-voltage models often have voltage ratings to be at 600 volts or lower.

As its name implies, these circuit breakers can protect a low-voltage environment with their pairs of contacts. Buyers should also be aware of the different models under this type, such as:

  • Plain break
  • Magnetic blowout
  • Air chute

3. Medium-Voltage Air Circuit Breakers

Unlike low-voltage air circuit breakers, medium-voltage variants can handle voltage ratings higher than 600 volts. In general, installers can use Eaton’s medium-voltage air breakers for applications like:

  • Generators
  • Motors
  • Feeder circuits
  • Distribution lines

4. Residential Circuit Breakers

Eaton compatible breakers used in a residential setting can be practical options for different applications. For instance, installers can use these models in an Eaton panel as arc fault circuit interrupters (AFCI) or ground fault circuit interrupters (GFCI).
