Will a QON42MS400 accept a QO2150, QO2175 and QO2200.

Yes, they can be used in QON 300 - 400 ampere loadcenters (single phase only) for new installations. In existing installations, QON, 300 - 400 ampere, single phase loadcenters, when mounted in a MH50 box (using a MHC50VF or MHC50VS cover), or when mounted in a MH53 box (using a MHC53VF or MHC53VS cover), the cover should be replaced with MHC50QVF, MHC50QVS, MHC53QVF or MHC53QVS, if over 10,000 amps fault current is available. If less than 10,000 amps fault current is available, the cover would not require replacement. If mounted in MH68 box with MHC68VF or MHC68VS cover, no replacement cover would be required, regardless of fault current available.
NOTE: THESE BREAKERS CANNOT BE INSTALLED IN 3-PHASE LOADCENTERS OR PANELBOARDS IN ANY CIRCUMSTANCE.
