The Masterpact® Circuit Breaker in Model 6 Motor Control Centers (MCCs) provides unique and exclusive features by combining the space saving, flexible Model 6 MCC platform with the feature-rich Masterpact NT and NW draw-out circuit breakers.

To best meet the needs of the global market, the Masterpact Circuit Breaker features a standard depth motor control center structure, which eliminates both extra depth enclosures and associative transitional units.

The compartmentalized design of the Model 6 MCC provides a greater level of protection by preventing inadvertent access as incoming (line) connection, circuit breaker, bus (load) connections and horizontal bus are isolated from each other. The barriers between compartments also reduce the potential of objects (tools) falling onto the bus.
