Product FAQs
4 answersWhich panelboards are compatible with the Square D A1B315?
This legacy circuit breaker is engineered specifically to mount into older Square D NA1B panelboards. It features a distinct long-body profile and will not fit into modern QO, NQ, or I-Line distribution systems.
Can I replace an A1B315 with a standard QOB breaker?
No. Although both are bolt-on breakers manufactured by Square D, the A1B series has a unique mounting configuration and long-body profile designed exclusively for NA1B panelboards. A standard QOB breaker is not physically interchangeable.
Is the Square D A1B315 breaker still in active production?
No, the A1B series is an obsolete product line. Replacements are sourced to maintain existing vintage commercial and industrial infrastructure that utilizes NA1B panelboards.
Does the A1B315 include a visual trip indicator?
Yes, this breaker features Square D Visi-Trip technology, which provides a clear visual indication when the breaker has tripped due to an overload or short circuit.

Although these breakers are refurbished they work great. It beats having to change the whole panel because of one breaker.
