Will any of the QO Enclosed Molded Case Switches accept QO or QOB breakers?

Issue:
Can miniature circuit breakers be installed in the enclosed molded case switch devices?

Product Line:
Molded Case Switches

Environment:
QO Enclosed Molded Switch Devices: QO260NATS, QO2000NS, QO200TR, QO200TRNM, QO200TRNM and QO2000NRB

Resolution:
No, neither QO or QOB circuit breakers can be used to replace the factory installed Molded Case Switches installed in the Enclosed Molded Case Switch devices.  Enclosed Molded Case Switch devices are NOT listed for overcurrent protection and thus they can NOT have circuit breakers installed.
