Product FAQs
6 answersWhat legacy Square D circuit breakers does the PowerPact H-Frame replace?
The PowerPact H-Frame series, including the HLP36020, is the modern replacement for legacy Square D 100A-frame breakers such as the FA, FH, and FY series. When upgrading, ensure your panel's mounting hardware and required interrupting capacity align with the new H-Frame specifications.
What does the L in the HLP36020 catalog number signify?
In the Square D PowerPact nomenclature, the L designates the breaker's interrupting rating tier. It indicates a high-capacity interrupting rating, specifically 125 kAIC at 240V and 100 kAIC at 480V, making it suitable for commercial and industrial systems with high available fault currents.
Are the lugs on the HLP36020 rated for aluminum conductors?
Yes, the factory-installed lugs on this breaker are AL/CU dual-rated, meaning they safely accept both aluminum and copper wiring. The terminals accommodate conductor sizes from 14 AWG up to 3/0 AWG.
Can I use the HLP36020 in a motor control center (MCC)?
Yes, this PowerPact H-Frame breaker is compatible with Square D motor control centers, switchboards, and standalone enclosures. It is commonly used for feeder and branch circuit protection in these industrial distribution systems.
Does the HLP36020 feature adjustable trip settings?
No, this specific model uses a traditional thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip functions. If your application requires adjustable trip curves or electronic sensing, you would need a PowerPact breaker equipped with a Micrologic trip unit.
Can this breaker be applied in 500VDC battery or solar applications?
Yes, the HLP36020 is fully rated for DC voltage applications up to 500VDC, where it provides a 50 kAIC interrupting rating. This makes it a safe and compliant choice for industrial DC control circuits, battery storage, and photovoltaic systems.
