Product FAQs
7 answersWhat does the BC suffix indicate in the FH26070BC part number?
The BC suffix indicates that this 2-pole breaker is factory-configured to connect to the B and C phases on the busbar of a Square D I-Line panelboard or switchboard.
Which panelboards are compatible with the FH26070BC circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes an I-Line style plug-in mounting system and is not compatible with standard QO, NQ, or Homeline load centers.
Is the Square D FH series still in active production, or is there a modern replacement?
The FH series is a legacy F-frame molded case circuit breaker. For new installations or infrastructure upgrades, Schneider Electric recommends transitioning to the modern PowerPact H-frame series, which offers equivalent ratings and I-Line compatibility.

Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting rating of 10kAIC.
Does this breaker have an adjustable trip unit?
No, the FH26070BC features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. It does not offer adjustable trip settings.
How does the interrupting rating of the FH26070BC change based on system voltage?
The breaker provides a maximum interrupting rating of 65kAIC at 240VAC. This rating decreases at higher voltages, offering 25kAIC at 480VAC and 18kAIC at 600VAC. Always verify the available fault current at your specific operating voltage.
