Product FAQs
7 answersCan I install the FH26020BC in a standard QO or Homeline load center?
No. The FH26020BC features an I-Line plug-in mounting style and is strictly compatible with Square D I-Line panelboards and switchboards. It will not fit in standard residential load centers.
What does the "BC" suffix indicate on the FH26020BC?
The "BC" suffix specifies the phase connection. This 2-pole breaker is factory-configured to connect to the B and C phases of the I-Line bus stack.
What is the modern replacement for the legacy FH26020BC breaker?
The Square D F-frame series is a legacy product. The direct modern replacement is the PowerPact H-frame series, which offers the same I-Line mounting and phase configurations for newer installations or upgrades.
How does the I-Line connection work on the FH26020BC?
The breaker uses a plug-on connection that ratchets firmly onto the I-Line bus stack using a screwdriver. This integral jaw design eliminates the need to manually assemble separate connectors to the bus bar.
Is the FH26020BC suitable for DC voltage applications?
Yes, in addition to its AC ratings up to 600VAC, this thermal-magnetic breaker is rated for up to 250VDC with a 10kA interrupting capacity, making it suitable for specific direct current systems.
What type of protection does the LI trip function provide on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. The fixed thermal element provides long-time protection against sustained overloads, while the fixed magnetic element provides instantaneous protection against short circuits.
Can I adjust the trip settings on the FH26020BC?
No. This breaker features a fixed thermal and fixed magnetic trip unit, meaning the overload and short circuit trip thresholds cannot be field-adjusted.
