A Molded-Case Circuit Breaker (MCCB) is a type of circuit protection device commonly used in electrical systems to safeguard against overloads and short circuits. Featuring a molded plastic or thermal-magnetic construction, MCCBs provide reliable and efficient protection for circuits in residential, commercial, and industrial applications. These breakers offer adjustable trip settings, quick response times, and high breaking capacities to ensure safe operation and prevent damage to equipment. With their compact design and versatile features, Molded-Case Circuit Breakers are essential components for ensuring electrical safety and system reliability.
