They can be converted to a main breaker load center, so they can be used to distribute the main supply of power if needed. These load centers have a neutral bar on either side of the bus bars, so compatible AFCI (arc fault circuit interrupter) or GFCI (ground fault circuit interrupter) breakers can plug directly onto the bus and neutral bars without requiring a pigtail connection. They're used with QO series circuit breakers to protect circuits from overcurrents. These load centers are used in residential, commercial, and industrial applications.
