Circuit Protection

Circuit Protection - Molded Case Circuit Breakers
Eaton Cutler-Hammer molded case circuit breakers are designed to provide circuit protection for low voltage distribution systems. Providing protection again overload in conductors and short circuits in connected apparatus, such as motors and motor starters. Molded case circuit breakers are designed for use in panelboards, switchboards, motor control centers, control panels, combination starters, individual enclosures, and bus duct plug-in units.

Specialty Breakers
Specialty Breakers are molded case circuit breakers which protect low-voltage distribution systems, while also meeting the specific needs of an application or market.

Miniature Circuit Breakers
A specific type of circuit breaker, used to switch and protect the lowest common distribution voltage in an electrical system. Generally used in a loadcenter, panelboard, or similar device. Eaton's Cutler-Hammer line of miniature circuit breakers are available with a wide selection of accessories, including shunt trips, and can be custom modified to meet special application requirements.

Miniature IEC Circuit Breakers
A specific type of circuit breaker, used to switch and protect the lowest common distribution voltage in an electrical system. Generally used in a loadcenter, panelboard, or similar device. Eaton's Cutler-Hammer line of miniature circuit breakers are available with a wide selection of accessories, including shunt trips, and can be custom modified to meet special application requirements.

Supplementary Protectors
Supplementary Protectors are ideal for providing protection in a multitude of applications. A current limiting design provides fast short circuit interruption that reduces the let-through energy which can damage the circuit.

Power Breakers
Low voltage air power circuit breakers are designed to provide circuit protection for low voltage power distribution systems. They safeguard connected apparatus against overloads and/or short circuits. They protect equipment and people.

Medium Voltage power circuit breakers Type VCP-W and W-VAC vacuum breakers provide centralized control and protection of medium voltage power equipment and circuits in industrial , commercial, and utility installations involving generators, motors, feeder circuits, and transmission and distribution lines.

Loadcenter Breakers
Generally used in loadcenters, panelboards, or similar device for electrical circuit protection. Eaton's Cutler-Hammer line of miniature loadcenter circuit breakers are available for a wide range of applications. The addition of Arc-Fault Circuit Interrupters (AFCI) represents a major improvement in electrical fire safety.

Replacement and Retrofit Breakers
Cutler-Hammer has a simple formula for meeting our customers needs- continuous new product innovation coupled with incomparable support of existing products. That is what our Direct Replacement Breakers are all about. Today, Cutler-Hammer continues to manufacture and support "Pre-Series C" breakers with the exact same vigor as we did 30 years ago when they were the latest and greatest of their day. Of course, this comes as no surprise to any of the thousands of loyal customers where millions of these breakers remain in operation today.
