Built for heavy-duty power distribution, the 60A HDL26060 features non-interchangeable thermal-magnetic trip units. It provides reliable long-time and instantaneous (LI) protection. The unit-mount configuration fastens into PowerPacT H-Frame enclosures and control panels. It acts as a functional cross-reference for legacy FAL22060 breakers, though dimensions differ. Handling 18kA faults at 480VAC, this component includes standard lugs and a reverse-feed design.
What wire size and material can be used with the HDL26060 lugs?
The standard lugs on this breaker accept 14 AWG to 3/0 AWG aluminum or copper (Al/Cu) wire.
Can the HDL26060 be installed in a Square D I-Line panelboard?
No, the HDL26060 is a unit mount (lug-to-lug) breaker designed for enclosures, switchboards, or DIN rail mounting. For an I-Line panelboard, you need the plug-on equivalent, catalog number HDA26060.
What does the D in the HDL26060 catalog number indicate?
In the PowerPacT H-Frame series, the D designates the interrupting rating level. A D-interrupting breaker provides 18kA at 480VAC. For a higher interrupting capacity, you would step up to a G-interrupting breaker (HGL26060), which offers 35kA at 480VAC.
What does the L in the HDL26060 catalog number mean?
The L indicates that the breaker is supplied with lugs on both the line and load sides, making it a unit mount breaker.
Is the HDL26060 suitable for reverse feeding?
Yes, standard unit mount PowerPacT H-Frame circuit breakers with fixed thermal magnetic trip units can be reverse fed.
Are the thermal and magnetic trip settings adjustable on the HDL26060?
No, this breaker features a fixed thermal and fixed magnetic trip unit. If your application requires adjustable trip settings, you will need a breaker equipped with a Micrologic electronic trip unit.
What is the difference between the HDL26060 and the HGL26060?
The HGL26060 has a higher interrupting rating (35kA at 480VAC) compared to the HDL26060 (18kA at 480VAC). Both share the same physical dimensions, 60A rating, and unit mount design.
