Will this replace a 200 amp breaker from my Siemens PL series load center? (Part number: P4040B1200CU) (I need to use a smaller main breaker per code.)
Asked by: Jason
Jason, In theory yes this will work, however the bus bar is rated for 200A, which usually isn't an issue for a lower amperage, its just not something we recommend. Thanks,

150 Amp Main Breaker Conversion Kit is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Works great, decent fit Installed this in a 200A main lug panel as part of my phased electrical service upgrade. This breaker conversion kit was required to safely connect my new panel to the service feed coming out of the meter pan. Later, I plan to upgrade service to 200A with a breaker/disconnect at the meter, and will remove this breaker from the panel.
