ML1 Circuit Breaker and SK4515

Issue:
Can we still get an SK4515 kit to mount an FAL circuit breaker into an ML-1 panelboard?

Product Line:
Obsolete panelboards, circuit breakers and accessories

Environment:
Square D ML style panelboards sold and supported from 1962 to 1968.

Cause:
Can a customer still get replacement branch breakers for the old style ML-1 panelboards?

Resolution:
This kit is good for replacing or adding circuit breakers to 10 5/8 deep ML panelboards manufactured from 1962-1968 and switchboards manufactured from 1962-1968, however it is now obsolete without replacement.

Consider replacing the panelboard with a new, current I-Line panelboard.
