Description
Part of the PowerPacT series, this 20-amp MCCB provides essential long-time and instantaneous (LI) trip functions. It is designed for demanding commercial and industrial applications requiring consistent electrical protection. The unit-mount configuration features factory-installed lugs for secure wire terminations in switchboards. It replaces discontinued FAL22020 and FAL24020 models. With a 14kAIC rating at 600VAC, the D-interrupting class ensures adequate fault clearance for standard systems.Specifications

Product FAQs
8 answersWhat type of mounting does the HDL26020 use?
This breaker features a unit-mount configuration, meaning it uses standard mechanical lugs on both the line and load sides for feed-thru connections. It is not designed for plug-in I-Line panelboards.
What types of enclosures and panels accept this breaker?
The HDL26020 is compatible with industrial control panels, switchboards, and standard PowerPacT H-Frame enclosures.
Is this circuit breaker suitable for DC applications?
Yes, it is rated for up to 250VDC with a maximum interrupting capacity of 20kA, making it suitable for specific direct current control and distribution systems.
Can the HDL26020 be reverse fed?
Yes, standard unit-mount PowerPacT H-Frame circuit breakers with fixed thermal-magnetic trip units are suitable for reverse feeding.
What is the difference between the HDL26020 and the HGL26020 or HJL26020?
The difference is the interrupting rating. The HDL frame has a D-interrupting rating of 25kA at 240VAC. The HGL and HJL models offer higher fault clearing capacities within the same physical footprint.
Does this breaker provide ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker with Long-Time and Instantaneous (LI) trip functions. It does not include equipment ground fault or arc fault protection.
What wire sizes are accepted by the standard lugs on this breaker?
The factory-installed mechanical lugs accept aluminum or copper wire ranging from 14 AWG to 3/0 AWG.
What is the recommended tightening torque for the lug terminals?
For the standard mechanical lugs, the tightening torque is 44 lbf-in (5 N.m) for 14 AWG to 10 AWG wire, and 124 lbf-in (14 N.m) for 8 AWG to 3/0 AWG wire.
