A DC molded case circuit breaker (MCCB) is a protective device designed to interrupt the flow of direct current (DC) in the event of an overload or short circuit. Unlike its alternating current (AC) counterpart, the DC MCCB is specifically engineered to handle the unique characteristics of DC power. The term "molded case" refers to the breaker's protective casing, which is made from a durable, insulating material that encases the internal components. This robust casing ensures the breaker's reliability and longevity.
