Freedom Arc-Resistant Motor Control Center (MCC)
This enhanced version of Eaton’s flagship Freedom MCC includes additional features specifically designed to contain the arc blast energy should an arc flash event be triggered within the assembly. The Freedom Arc Resistant MCC has a Type 2 accessibility rating, meaning that arc resistant designs or features are present on the front, back, and sides of the assembly. This Type 2 rating translates to enhanced safety around the entire perimeter of the MCC should an arc flash event occur.
