BJA34110 SQUARE D 3P 110A 480/277V 65KA I LINE

The Square D BJA34110 is a 3-pole, 110A, 480/277V molded-case circuit breaker from the BJA (I-Line) frame series, rated at an impressive 65kA interrupting capacity. As an I-Line plug-in breaker, it is designed to mount in Square D I-Line panelboards and switchboards — commercial and industrial distribution equipment — rather than residential loadcentres. It is not compatible with QO or Homeline loadcentres.

Specific compatible Square D I-Line panelboard families include NF, NQ, and PQ series equipment that accept I-Line plug-in breakers in the appropriate bus rating. Panel and bus ampacity must meet or exceed the breaker's load requirements. Send us your panelboard model and we'll confirm fit before you order.
