The main circuit breaker within the AFD panel is affixed
with a dial, labeled “Ir”, to set the trip current of the breaker.
See tables below for the factory “Ir” dial setting for 400 amp
and 600 amp (L-frame) circuit breakers, and for the 800
amp and 1200 amp (P-frame) circuit breaker “Ir” dial
settings. These values are based on the panel SRRL and
IVLT values found on the unit nameplate.
