Product FAQs
7 answersHow does the HGA260351 connect to the panelboard?
It utilizes the Square D I-Line mounting system. The line side features plug-on jaws that connect directly to the panelboard bus stack, while the load side uses mechanical lugs for wire termination. A mounting bracket secures the breaker to the panel interior.
What does the 1 suffix mean in the HGA260351 catalog number?
The 1 suffix specifies the bus phase connection for this 2-pole I-Line breaker. It indicates that the plug-on jaws are configured to connect to the A and B phases of the panelboard bus.
What interrupting rating does the G designate in the HGA260351 part number?
The G indicates the specific interrupting rating tier within the PowerPacT H-Frame family. It provides a maximum capacity of 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
What replacement load lugs are compatible with this breaker?
The standard mechanical load lugs for this 35A H-Frame breaker are part number AL150HD. These lugs accept 14 AWG to 3/0 AWG aluminum or copper conductors.
Can the HGA260351 be installed in a standard Square D QO or Homeline load center?
No. This is an I-Line molded case circuit breaker designed exclusively for commercial I-Line panelboards and switchboards. It will not fit in residential QO or Homeline enclosures.
What protection functions are included in the LI trip unit?
The LI designation stands for Long-Time and Instantaneous trip functions. The thermal-magnetic trip unit provides fixed thermal protection for continuous overloads and adjustable magnetic protection for short-circuit faults.
Is the HGA260351 suitable for reverse feeding in an I-Line panel?
Yes, Square D PowerPacT H-Frame thermal-magnetic breakers can be reverse fed. When used as a backfed main in an I-Line panelboard, the breaker must be explicitly labeled as the Main Breaker to comply with service entrance requirements.
