Can the AL400L61K3 lug be installed on the 400 amp or 600 amp Powerpact L frame breaker?
Yes, the AL400LI61K3 may be used on the 400A and 600A L-frame circuit breakers (the lug is standard on the 250A L-frame). The lug kit itself includes three separate lugs, and each lug accepts the following wire range:
(1) #2 AWG to 500 kcmil Al,
or (1) #2 AWG to 600 kcmil Cu
It may be used on either end of a unit mount breaker (one kit per end, so 2 kits may be required), and on the load end of an I-line breaker (one kit is required). For field installation, order the appropriate kits for the breaker. For factory installation, order the breaker with suffix LY.
NOTE: The above information also applies to lug kit 32508.
