Molded Case Circuit Breakers
Both commercial and industrial settings require a vital electrical protection device, and this role is served by a molded case circuit breaker (MCCB). While MCCBs can seem visually similar to their smaller relatives, miniature circuit breakers (MCBs), they have some key functional and operational differences. The MCCB is used to protect a wide variety of electric circuits and the equipment that those circuits feed. MCCBs can provide adjustable trip settings, which makes them extremely versatile in the field. They are also typically used in applications that carry substantially higher current than MCBs or conduct much-higher-ampere on-off action.
These types of circuit breakers can be found in many different places, performing many different functions. For instance, they might be used in a "motor control center" to protect the circuit serving motor loads. Transported distribution systems (like those on ships) also use these units for the same reason. Additionally, molded case circuit breakers play a vital role on our electrical utility system. Within a typical "switchgear," you will likely find this variety of circuit breaker in many locations, responsible for serving in various different overcurrent protection capacities.
