Product FAQs
7 answersWhat enclosures or panels are compatible with the FHL26090?
This unit mount breaker is designed for use in compatible Square D enclosures, switchboards, and panelboards. It features a feed-thru lug design and is not compatible with I-Line plug-on panelboards.
What wire sizes and materials are accepted by the FHL26090 lugs?
The factory installed lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire.
Is the FHL26090 a current or legacy model?
The FHL26090 is part of the legacy F-Frame series of molded case circuit breakers. For new installations or system upgrades, Schneider Electric designates the PowerPact B-Frame series as the modern replacement for F-Frame applications up to 125 amps.
What does the LI trip function on the FHL26090 indicate?
The LI designation means this thermal magnetic breaker provides Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function provides immediate tripping during severe short circuits. Both thermal and magnetic trip settings are fixed on this model.
Can the FHL26090 be used in DC applications?
Yes, this breaker is rated for use in DC circuits up to 250VDC, where it provides a 10kA interrupting capacity.
How does the FHL series differ from the standard FAL series?
The FHL series features a higher interrupting capacity than the standard FAL series. The FHL26090 provides a 25kA interrupting rating at 480VAC, making it suitable for commercial and industrial systems with higher available fault currents.
What are the standard safety precautions for installing the FHL26090?
Installation must be performed by a qualified electrical professional. Always verify that the power source is completely de-energized and locked out before installing or servicing the breaker to prevent arc flash and shock hazards.
