Product FAQs
6 answersHow does the HGA260452 mount into a panelboard?
It utilizes the Square D I-Line mounting system, which features plug-on phase connections that snap directly onto the panelboard bus. This allows for faster installation in I-Line panelboards and switchboards compared to traditional bolt-on breakers.
What does the G in the HGA260452 part number indicate?
The G designates the interrupting rating level within the PowerPacT H-Frame family. For this breaker, it provides a 65kA rating at 240VAC, 35kA at 480VAC, and 18kA at 600VAC.
Are the trip settings on the HGA260452 adjustable?
No. This breaker features a thermal-magnetic trip unit with fixed thermal and fixed magnetic settings for both long-time and instantaneous protection.
Can this breaker be used in DC applications?
Yes, it is rated for DC systems. It provides an interrupting capacity of 20kA at both 250VDC and 500VDC.
Can the HGA260452 replace older Square D F-Frame breakers?
Yes. The PowerPacT H-Frame series is the direct, modern replacement for legacy Square D F-Frame (FA and FH) circuit breakers in I-Line panelboards.
What does the LI trip function code mean on this breaker?
The LI designation means the breaker provides Long-Time (L) and Instantaneous (I) overcurrent protection. Long-time protects against sustained overloads, while instantaneous protects against short circuits.
