Specialty Breakers

Eaton offers a variety of molded case circuit breakers, with designs that cater to individual applications. These include engine generator versions, built for reliability and robustness. They are engineered to handle the demands that generators impose — specifically high starting currents and lots of on-off cycling. Their design allows them to withstand the rigors of somewhat of an incognito life in many types of outdoor environments (weather), as well as inside engines (heat).

Eaton's engine generator molded case circuit breakers have this much going for them. Navy and Marine molded case circuit breakers are engineered to withstand environments far harsher than typical generator installs—for instance, saltwater immersion—or high humidity or vibrations found in naval operations.

The solar complete assortment from Eaton offers arc fault protection, high interrupting ratings, and compatibility with many photovoltaic (PV) system components. These breakers ensure safe and efficient operation of solar power installations by giving reliable protection against overcurrents, short circuits, and other kinds of electrical faults.

What is a Circuit Breaker?

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.
