The MXL breaker in an MA1000AWK enclosure shows an AIC rating of 50K at 480V on drawing #3082. Elsewhere the breaker is 65K at this level. Does the enclosure reduce the AIC?

Yes. The AIC is reduced because of mounting the breaker inside of an enclosure.
NOTE: THE MA1000F, MA1000S, MA1000R, MA1000AWK AND MA1000DS ENCLOSURES ARE OBSOLETE AND NO LONGER AVAILABLE AS OF FEBRUARY, 2009. CONSIDER USING THE M OR P FRAME POWERPACT CIRCUIT BREAKER IN THE M800 OR P1200 SERIES OF ENCLOSURES.
