Issue:
What is the replacement for a Q1L circuit breaker in a circuit breaker enclosure?

Product Line:
Circuit Breakers

Environment:
Applies to Q1L circuit breakers (third letter is an L).
Does not apply to Q1 breakers with TF suffix (main breaker in load centers).

Cause:
Q1L circuit breaker replacement

Resolution:
The Q1L circuit breakers are obsolete, and no longer available. This breaker had lugs at each end for cable connection. The breaker fastened to the enclosure using small metal clips. It did not plug-on or bolt-on to the panel bus.

Due to the physical size of the Q1L breaker and how it was installed, current breakers will not fit in the same place in the existing enclosure. We recommend replacing the Q1L breaker and the related enclosure with currently manufactured equipment.
