Product FAQs
8 answersHow is the HDL26070 mounted in an enclosure?
This breaker features a unit-mount design, meaning it is installed using fasteners and wired directly via the included feed-thru lugs rather than plugging into a busbar.
What types of equipment are compatible with the HDL26070?
It is designed for use in industrial control panels, switchboards, and dedicated PowerPacT H-Frame enclosures.
What are the wire size requirements for the standard lugs on this breaker?
The factory-installed lugs accept both aluminum and copper conductors ranging from 14 AWG to 3/0 AWG.
What does the D in the HDL26070 part number indicate?
In the PowerPacT H-Frame series, the D designates the interrupting rating tier, which provides 18kA at 480VAC, 25kA at 240VAC, and 14kA at 600VAC.
Can the thermal or magnetic trip settings be adjusted on this breaker?
No, this specific model features a fixed thermal and fixed magnetic trip unit. If adjustable settings are required, you will need to look at breakers with electronic trip units, such as the Micrologic series.
Is the HDL26070 suitable for reverse-fed applications?
Yes, standard thermal-magnetic PowerPacT H-Frame breakers like this model are suitable for reverse feeding.
Can the HDL26070 replace a legacy Square D F-Frame breaker?
The PowerPacT H-Frame series is the modern replacement for legacy F-Frame breakers. However, the physical dimensions and mounting footprints are different, so modifications to the panel or a retrofit kit may be required.
Can this breaker be used in DC applications?
Yes, the HDL26070 is rated for use in DC systems up to 250VDC, with an interrupting rating of 20kA.
