Eaton Molded Case Circuit Breakers

Eaton molded case circuit breakers (MCCBs) are electrical protection devices that are designed to provide overcurrent protection and circuit interruption in electrical distribution systems. They are commonly used in industrial, commercial, and residential applications to protect electrical circuits and equipment from damage caused by short circuits, overloads, and other electrical faults.

MCCBs consist of a molded case that houses the operating mechanism, trip unit, and current-carrying components. The case is typically made of a high-impact, flame-resistant thermoset material that provides excellent protection against environmental hazards such as dust, moisture, and chemicals.

Eaton offers a wide range of MCCBs with various trip units, current ratings, and interrupting capacities to meet different application requirements. The trip unit is the brain of the circuit breaker, and it is responsible for detecting overcurrents and triggering the opening of the breaker contacts. Eaton MCCBs are available with different types of trip units, such as thermal-magnetic, electronic, and microprocessor-based trip units, to provide precise and reliable protection for different types of loads and applications.

In addition, Eaton MCCBs are designed with a range of features to enhance their performance and usability. These features may include adjustable trip settings, visual indicators for circuit status, interchangeable trip units, and various accessories to facilitate installation and maintenance.
