Eaton Molded Case Circuit Breakers
Eaton's molded case circuit breakers are known for being dependable, adaptable, and offering up-to-the-minute protection in many different electrical setups. They're the first line of defense, if you will, when it comes to resolving problems with electrical circuits that have become overloaded, short-circuited, or "ground-faulted," or which have had their conductors come into contact with something that they weren't supposed to.
The G series, C series, and Power Defense series are the most well-known types of molded case circuit breakers that Eaton offers. They are often selected over other breakers because they offer features that other breakers do not, and they do these things at varying price points. For many applications, NEMA (National Electrical Manufacturers Association) operators select the compact G molded case circuit breaker; it provides a much smaller footprint than most other breakers and is ideal for use in MCCs (motor control centers) or other panels that have minimal space left in them for a breaker. The C molded case circuit breakers are the most commonly utilized line of three-phase breakers in the industry today.

What is a Circuit Breaker?
There are two different types of technologies that are commonly used in circuit breakers.
Magnetic Breakers
Magnetic Breakers are designed to react to short circuits or sharp spikes in voltage and current. The more current that passes through the breaker’s electromagnet, the stronger the magnet becomes. When the current exceeds the rating for that particular breaker, the magnetic force becomes strong enough that it will pull the contact back and disconnect it from the other contact, disconnecting power from the device.
Thermal Protection Breakers
Thermal Protection Breakers protect against a sustained overcurrent, or a higher current, for a longer period of time. Thermal protection uses a Bimetal strip that will bend the contacts away from each other to disconnect power. Thermal Magnetic Breakers are the most common type of circuit breakers. They combine magnetic technology to protect against short circuits or sharp spikes and thermal technology that protects against sustained overcurrent for a long period of time.
