Molded case circuit breaker


The traditional molded – case circuit breaker uses electromechanical (thermal magnetic) trip units that may be fixed or interchangeable. An MCCB provides protection by combining a temperature sensitive device with a current sensitive electromagnetic device. Both these devices act mechanically on the trip mechanism.

Molded case circuit breakers are a type of electrical protection device that is commonly used when load currents exceed the capabilities of miniature circuit breakers. They are also used in applications of any current rating that require adjustable trip settings, which are not available in plug-in circuit breakers . An overview of molded case circuit breaker components, applications, mounting specifications and environments.

Includes an MCCB Video Overview. Miniature and molded – case circuit breakers are usually discarded when the contacts have worn, but power circuit breakers and high-voltage circuit breakers have replaceable contacts. When a high current or voltage is interrupte an arc is generated. The length of the arc is generally proportional to the voltage while the . Geared for Industrial, Commercial and OEM applications, .
