Product FAQs
8 answersWhat type of panelboards accept the HGA260902 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line plug-on connection on the line side and standard lugs on the load side, making it incompatible with standard bolt-on or load center panels.
How does the I-Line connection work on this breaker?
The I-Line mounting system uses a plug-on design for the line side, allowing the breaker to snap directly onto the panelboard bus assembly. The load side utilizes standard mechanical lugs for your outgoing wire terminations.
Is the HGA260902 suitable for reverse-fed applications?
Yes, this thermal-magnetic breaker is suitable for reverse feeding. Because it does not contain an electronic trip unit with directional sensitivity, you can safely supply power to either the line or load terminals.
What protection does the LI trip function provide?
The LI designation stands for Long-Time and Instantaneous trip functions. Long-Time provides overload protection by tripping when current exceeds the rating for a sustained period, while Instantaneous offers short-circuit protection by tripping immediately during a massive current spike.
Can I adjust the trip settings on the HGA260902?
This breaker features a fixed thermal setting for overload protection, which cannot be changed from its 90A rating. However, it includes an adjustable magnetic trip setting, allowing you to fine-tune the instantaneous short-circuit response to suit your specific application.
Do I need to change the lugs to use aluminum wiring?
No, the factory-installed mechanical lugs on the load side are dual-rated for both aluminum and copper conductors. They accept wire sizes from 14 AWG up to 3/0 AWG.
Does this 2-pole breaker require a neutral connection?
No, this is a 2-pole thermal-magnetic breaker designed to protect two ungrounded hot conductors. It does not require a neutral connection for its internal trip mechanisms to function properly.
What interrupting rating tier does the G in HGA260902 represent?
In the Square D PowerPacT H-Frame series, the G designates the specific interrupting capacity tier. For this model, it indicates a rating of 65 kA at 240V AC, 35 kA at 480V AC, and 18 kA at 600V AC.
