What does suffix 5251 indicate on QOU breakers?
Issue:
What is the -5251 suffix on QOU breakers?

Product Line:
Circuit Breakers

Resolution:
Suffix 5251 indicated a threaded mounting foot used on 10-60 A QOU breakers, and is similar to the 3100 suffix that we use now.
It is obsolete, and the customer should use the 3100 suffix or order the standard mounting feet (QOUMF1 for single pole, QOUMF2 for 2 pole, or QOUMF3 for 3 pole).
