Sensor IQ 48 Channel Main Breaker and Main Fuse Options
If a 48-channel Sensor IQ panel is fed with a 400A feed, a 65kA breaker must be used. However, if you are feeding a Sensor IQ 48-channel panel with a 100A or 200A feed, the 22kA breakers are OK to use.
Breakers are rated per pole/phase. So, a Main Breaker: 277/480V (240/415V), 100A will support 100Aper phase NOTE: Per the NEC, a 100A breaker can only be loaded to 80% or in your case(100A main) 80A per phase.
