Serving as a robust overcurrent solution, this 90A F-Frame breaker delivers dependable long-time and instantaneous protection for commercial power systems. It integrates smoothly into older Square D panelboards and switchboards that utilize a unit mount design. For modernizations, this specific configuration is replaced by the PowerPact HGL26090 series. The breaker features a Visi-Trip indicator for rapid fault identification and carries a standard HACR rating for HVAC applications.
Is the Square D FAL26090 still manufactured, or is there a direct replacement?
The FAL series is a legacy F-Frame breaker and is no longer actively manufactured by Square D. For modernizations or new installations, the PowerPact H-Frame series serves as the current replacement, though mounting dimensions and backpan drilling may vary.
What does Unit Mount mean for the FAL26090, and can it be used in an I-Line panel?
Unit mount indicates that this breaker bolts directly to a backpan or mounting surface and uses wire lugs on both the line and load sides. It does not have plug-on jaws and cannot be converted for use in an I-Line panelboard.
Can the FAL26090 be used in direct current applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC. When wiring for DC applications, consult the manufacturer guidelines to ensure the poles are connected correctly for the system voltage.
What wire sizes are compatible with the lugs on the FAL26090?
The included feed-thru lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Always torque the terminals to the exact specifications listed on the breaker faceplate to comply with NEC requirements.
What types of equipment are compatible with the FAL26090?
This 90A F-Frame breaker is designed for use in older Square D switchboards, control panels, and standalone enclosures that accommodate unit-mount breakers.
Are the trip settings adjustable on the FAL26090?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. It does not offer adjustable dials for tuning the trip curve.
