Description
Providing essential overcurrent protection, the Square D FHL36030 is a 3-pole, 30A legacy F-frame molded case circuit breaker. It is engineered for industrial applications. The unit-mount design allows for integration into Square D enclosures and switchboards. For modern replacements, the HGL36030 is the recommended substitute. Equipped with fixed thermal and magnetic trip elements, it delivers reliable long-time and instantaneous (LI) functions with a 25kAIC rating at 480VAC.Specifications

Product FAQs
10 answersWhat is the difference between the Square D FHL and FAL series breakers?
Both are F-Frame molded case circuit breakers, but the FHL series features a higher interrupting rating (up to 65kAIC at 240V and 25kAIC at 480V) compared to the standard FAL series.
What is the modern replacement for the legacy FHL36030 circuit breaker?
The legacy F-frame FHL36030 is typically replaced by the PowerPact H-frame series, specifically the HGL36030, which offers updated trip units and a more compact footprint while maintaining the 30A, 3-pole, 600VAC rating.
Can the FHL36030 be reverse fed?
Yes. Because this thermal-magnetic breaker does not have Line and Load markings, it can be reverse fed for supply-side applications, provided it is properly labeled in the enclosure according to NEC requirements.
Is the FHL36030 rated for use on DC electrical systems?
Yes, this breaker is rated for up to 250VDC with a 10kAIC interrupting rating, making it suitable for specific direct current applications.
What wire sizes are accepted by the FHL36030 lugs?
The factory-installed lugs accept 14 AWG to 4 AWG copper or aluminum conductors. Ensure proper torque is applied during installation to prevent thermal issues.
Will the FHL36030 fit into an I-Line panelboard?
No. The FHL36030 is a unit-mount (feed-thru) circuit breaker designed for standard enclosures, switchboards, and control panels. It does not have the plug-on jaw connections required for I-Line panelboards.
What safety precautions are required before installing or replacing this breaker?
Always de-energize the panel or switchboard before installation. Verify that power is off using a properly rated voltage sensing device, and follow all OSHA lockout/tagout procedures to prevent accidental re-energization.
What trip functions are included in the FHL36030?
This breaker features a fixed thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions, providing dual-layer protection against sustained overloads and short-circuit events.
Can this breaker be used for HVAC equipment?
Yes, the FHL36030 is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires a 30A, 3-phase disconnect.
What does a feed-thru connection type mean for this breaker?
A feed-thru connection means the breaker uses standard lugs on both the line and load sides, rather than plugging onto a busbar. This makes it ideal for mounting in standalone enclosures or control panels.
