Product FAQs
6 answersWhat type of panelboards will the HLA260304 fit?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on line side connection and will not fit standard QO, NQ, or NF series load centers.
What are the torque specifications for the load-side lugs?
The factory-installed AL150HD mechanical lugs require a tightening torque of 44.3 lb-in (5 N.m) for 14 to 10 AWG wire, and 123.9 lb-in (14 N.m) for 8 to 3/0 AWG copper or aluminum conductors.
Can the HLA260304 be used to replace older Square D breakers?
Yes, the PowerPacT H-frame series serves as the modern replacement for legacy Square D F-frame I-Line breakers, such as the FA26030. The H-frame provides upgraded thermal-magnetic protection while maintaining I-Line bus compatibility.
What does the L interrupting class indicate on this H-frame breaker?
The L in the HLA part number designates a high-tier interrupting capacity. It provides fault protection rated at 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC, making it suitable for systems with high available fault currents.
How is the line-side connection made on this breaker?
The HLA260304 utilizes an I-Line style plug-in connection. The line side features specialized jaws that clamp directly onto the panelboard bus assembly, eliminating the need for line-side wire terminations.
What does the final digit in the HLA260304 catalog number signify?
The final digit indicates the specific phase connection for the I-Line bus. For this 2-pole breaker, the 4 means it is configured for a BC phase connection on the panelboard.
