Engineered for industrial applications, the Square D HLP36060 is a 60A, 3-pole MCCB from the PowerPacT H-Frame family. This unit-mount breaker installs into Square D enclosures and switchboards. It features load-side lugs and serves as a substitute for HLL36060 models. Rated for 100 kAIC at 480VAC, it delivers L-class interrupting capacity for high-fault environments. The unit includes a Visi-Trip indicator and current-limiting capabilities.

Product FAQs
8 answers
What is the difference between the HLP36060 and an I-Line breaker?
The HLP36060 is a unit-mount (bolt-on) breaker designed to be hard-wired or bolted into switchboards, enclosures, and motor control centers. It does not have the plug-on jaw connections required for Square D I-Line panelboards.
What does the "L" in the HLP36060 part number signify?
In the Square D PowerPacT nomenclature, the "L" indicates the breaker's interrupting rating tier. For this model, it signifies high interrupting capacities of 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC.
Can the HLP36060 be used in DC voltage systems?
Yes, this thermal-magnetic breaker is rated for direct current applications. It provides an interrupting capacity of 20kA at 250VDC and 50kA at 500VDC.
Are the trip settings adjustable on the HLP36060?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory-set and cannot be adjusted in the field.
What frame size category does the HLP36060 fall under?
It is part of the Square D PowerPacT H-Frame series. This compact molded case frame size is standardized for breakers ranging up to 150 amps, allowing for consistent mounting dimensions across different amperages.
Does the HLP36060 come with lugs, and what wire types are supported?
Yes, the breaker includes factory-installed lugs on both the line and load sides. They are dual-rated for either aluminum or copper conductors ranging from 14 AWG to 3/0 AWG.
Is the HLP36060 suitable for international applications?
Yes, Square D PowerPacT H-Frame breakers are designed for global compliance. They typically carry UL, CSA, NOM, and IEC certifications, making them suitable for a wide range of commercial and industrial installations.
Can the HLP36060 replace older Square D F-Frame breakers?
Yes, the PowerPacT H-Frame series is the modern replacement for legacy Square D F-Frame (FAL or FHL) circuit breakers. However, because the physical dimensions and mounting footprints differ, retrofitting an HLP36060 into an older enclosure may require hardware modifications or a retrofit kit.
