The FH26050BC SQUARE D 2P 50A 600/347V BC PH I LINE circuit breaker offers reliable protection for your electrical systems. Designed for use in commercial and industrial applications, this two-pole breaker ensures optimal performance with a 50A rating. Ideal for panel boards, it is both durable and efficient to meet your needs.
The FH26050BC is an I-Line plug-in breaker designed for Square D I-Line panelboards and switchboards rated for 600V commercial/industrial distribution. It is not interchangeable with QO or Homeline residential loadcentres. Share your panelboard model number with us and we'll verify compatibility.
The "BC" suffix indicates the Phase I line configuration — specifically the phasing/buswork orientation (phases B and C) the breaker is designed to connect to within the I-Line panelboard. It's important that this matches your panel's bus arrangement; using the wrong phase configuration can result in improper installation. Contact us if you're unsure which phase configuration your panel requires.
The Square D FH I-Line series breakers can be difficult to source as commercial electrical infrastructure ages. Northern Breaker Group specializes in obsolete and hard-to-find breakers — if the FH26050BC is no longer available through standard channels, we can often locate new-old-stock or factory-reconditioned units.
