Product FAQs
6 answersWhat phase connection does the HGA261501 use in I-Line panelboards?
The "1" suffix in the catalog number indicates a dedicated AB phase connection. It is designed exclusively for plug-in mounting on the A and B phases of Square D I-Line panelboards and switchboards.
Which legacy Square D breaker does the HGA261501 replace?
This PowerPacT H-frame breaker serves as a direct replacement for the older KA26150AB 2-pole, 150A I-Line circuit breaker.
How is the HGA261501 wired and mounted?
The line side features a plug-in jaw connection that mounts directly onto the I-Line bus. The load side includes factory-installed lugs that accept 14 AWG to 3/0 AWG copper or aluminum wire.
Can this breaker be used in DC power systems?
Yes, the HGA261501 is rated for DC applications up to 250VDC, delivering a 20kA interrupting rating for DC circuits.
What does the LI trip function indicate on the HGA261501?
The LI code means the breaker provides Long-Time (L) and Instantaneous (I) protection. It uses a thermal-magnetic trip unit with a fixed thermal element for overloads and an adjustable magnetic element for short circuits.
Does this breaker require a separate mounting bracket for installation?
No, the HGA261501 features an integrated I-Line plug-in design. It mounts directly to the busbars of a Square D I-Line panelboard or switchboard without the need for additional mounting hardware.
