Product FAQs
4 answersWhich load centers are compatible with the UBITBA120L breaker?
This plug-on breaker is classified for use in Challenger Type A, Crouse-Hinds Type MH, Murray Type MP, and Thomas & Betts Type A load centers.
What does the L designation mean on the UBITBA120L?
The L indicates a left-side mounting clip. Because these are half-inch thin breakers, panels often require a specific left clip or right clip (UBITBA120R) depending on the physical slot position being populated.

Yes, the UBITBA series is manufactured as a direct, safety-agency-listed replacement for older Challenger Type A and Crouse-Hinds Type MH circuit breakers.
Are UBITBA classified replacement breakers safety certified?
Yes, these replacement breakers are ETL listed to UL Standard 489 for molded case circuit breakers, ensuring they meet current safety requirements for use in specified older panels.
