Description
Part of Square D's legacy F-Frame lineup, the FHL36015 is a 3-pole, 15A molded case circuit breaker designed for commercial facilities. It utilizes fixed thermal-magnetic trip technology for essential LI protection. Equipped with line and load lugs (indicated by the 'L' prefix), this unit-mount MCCB installs into Square D switchboards. It is replaced by the HGL36015, requiring a retrofit kit. Rated for 25 kAIC at 480V, this high-interrupting breaker ensures robust fault clearing.Specifications

Product FAQs
6 answersWhat distinguishes the FHL36015 from the FAL36015?
The FHL series is the high-interrupting version of the standard FAL F-frame breaker. While both share the same physical dimensions and 15A rating, the FHL36015 provides a 25kAIC rating at 480VAC, compared to the 18kAIC rating of the standard FAL.
How is the FHL36015 mounted in an electrical system?
This breaker features a unit-mount, feed-thru configuration. It is designed to be bolted or mounted directly to the backpan of Square D enclosures, switchboards, or motor control centers, rather than plugging onto a bus like I-Line breakers.
Is the FHL36015 considered a current production breaker?
The FHL series is part of the legacy Square D F-frame family. For new installations requiring a 15A, 3-pole unit-mount breaker, Schneider Electric typically recommends the modern PowerPact H-frame series, though F-frame breakers remain widely used for direct replacements in existing equipment.
Are the lugs on the FHL36015 rated for aluminum wire?
Yes, the standard factory lugs are dual-rated for both copper and aluminum conductors. They accommodate wire sizes ranging from 14 AWG to 4 AWG.
What is the DC interrupting capacity for the FHL36015?
When applied in 250VDC systems, this thermal-magnetic breaker provides a 10kA interrupting rating. Ensure your specific DC application aligns with the fixed long-time and instantaneous trip characteristics.
Can the FHL36015 be installed in a Square D I-Line panelboard?
No, the FHL36015 is a unit-mount breaker with feed-thru lugs and is not compatible with I-Line bussing systems. I-Line panelboards require breakers with specialized plug-on jaw connectors, whereas this model is designed to be bolted directly to a backpan.
