Internal Arc Classification IAC A-F, A-FL and A-FLR are defined in IEC 62217-200 and help to define internal arc performance of medium voltage or high voltage switchgear.

The following definitions are described as:

• A   switchgear installation in rooms with access for authorized personnel, closed electrical service location
• A-F  switchgear front (F-front) only protection for users
• A-FL  switchgear front and side (F-front, L-lateral) protection for users
• A-FLR  all sided switchgear (F-front, L-lateral, R-rear) protection for users

• Ringmaster has A-F or A-FLR designation
• GenieEvo has A-F or A-FLR designation
• MCset has A-FL or A-FLR designation
