Molded Case Circuit Breakers

Molded case circuit breakers (MCCBs) provide overcurrent and short circuit protection for electrical systems in residential, commercial, and industrial settings. They are designed and tested for use in a variety of applications where reliable and safe operation under conditions of fault or excessive current flow is essential for electrical system integrity. With their robust molded case design, MCCBs are highly durable and capable of withstanding the demands of a wide range of applications—everything from branch circuit protection in a home to high-capacity circuits in an industrial environment.

MCCBs usually have thermal-magnetic mechanisms or electronic trip units for exact and effective protection. Thermal-magnetic MCCBs employ thermal overload protection elements and magnetic elements for short-circuit protection. These basic mechanisms still provide the kinds of versatile, dependable, and multipurpose features that make MCCBs suitable for a range of uses.
