Molded Case Circuit Breakers

What are molded case circuit breakers?

Molded case circuit breakers are some of the most common circuit breakers around. When your mini circuit breaker just doesn’t cut it anymore, a molded case circuit breaker, or MCCB for short, might be what you’re looking for next. While they’re used for many industrial applications due to their durability and their high current rating capacity, they are also used in residential applications.

Molded case circuit breakers protect against thermal overloads, short circuits, and ground faults. They also have adjustable trip settings, which makes them one of the more common choices of circuit breakers. While a molded case circuit breaker functions the same as any breaker, it also uses a combination of thermo-magnetic and electromagnetic trip mechanisms to effectively protect your electrical system.

Molded case circuit breaker uses and applications

Available in a wide variety of amp ratings, from as low as 75A to as high as 1200A, molded case circuit breakers can be used in many low and medium voltage heavy duty applications, including industrial and commercial applications. They are commonly installed in control panels, switchboards, and panelboards.
