Product FAQs
5 answersWhat type of panelboards accept the HDA260351 breaker?
This breaker mounts exclusively into Square D I-Line panelboards and switchboards. It utilizes a plug-on design specific to the I-Line bussing system and is not compatible with NQ, NF, or QO load centers.
What does the trailing 1 in the HDA260351 catalog number mean?
The 1 signifies that this 2-pole breaker is factory-configured for an A-B phase connection on the I-Line bus.
What are the lug torque requirements for this breaker?
For the standard AL150HD lugs, tighten 14 to 10 AWG wire to 44 lb-in (5 N.m). For larger 8 to 3/0 AWG wire, tighten to 124 lb-in (14 N.m). Always use properly stripped aluminum or copper conductors.
Which obsolete Square D breaker does the HDA260351 replace?
This PowerPacT H-frame breaker is the direct manufacturer replacement for the discontinued F-frame FA26035AB circuit breaker.
Are the thermal and magnetic trip settings adjustable on this model?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous (LI) protection parameters are factory-set and cannot be modified in the field.
