As a bolt-on MCCB, it is designed for installation in commercial and industrial panelboards and switchboards that accept KA-frame breakers — not residential loadcentres. It is commonly used for feeder and branch-circuit protection in Square D NF, I-Line, and compatible bolt-on panelboard assemblies.

Frame compatibility depends on the specific panelboard's breaker mounting and bus configuration. Send us your panelboard model and we'll confirm fitment.
