How can we help you today?

Will any of the QO molded case switch enclosures accept QO or QOB breakers?

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

Product Line:
Molded Case Switches

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 cannot have circuit breakers installed.
