Product FAQs
6 answersWhat is the difference between the Square D FAL36050 and the FHL36050?
The FHL36050 features a higher interrupting rating of 25kA at 480VAC and 65kA at 240VAC, whereas the standard FAL36050 is rated for 18kA at 480VAC and 25kA at 240VAC. Both share the same physical dimensions and mounting style.
Is the FHL36050 an I-Line or unit-mount circuit breaker?
The FHL36050 is a unit-mount circuit breaker designed for feed-thru connections using lug terminals. It does not have the plug-on jaw connectors required for I-Line panelboards.
What wire sizes are compatible with the FHL36050 lugs?
The factory-installed lugs on this breaker accept 14 AWG to 1/0 AWG copper or aluminum conductors.
Can the FHL36050 be used in DC applications?
Yes, this breaker is rated for DC circuits up to 250VDC, providing a 10kA interrupting capacity. Ensure proper wiring configurations for DC systems as specified by the manufacturer.
Is the Square D F-frame series still in active production?
The legacy F-frame series, including the FHL36050, has been superseded by the modern PowerPact H-frame series. Direct replacement with an H-frame breaker requires specific mounting adapters or enclosure modifications.
Can I install the FHL36050 in a standard residential load center?
No, the FHL36050 is a molded case circuit breaker designed for industrial enclosures, switchboards, and motor control centers. It is not compatible with standard QO or Homeline residential load centers.
