Product FAQs
8 answersWhat type of panelboards accept the HJA260151?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection and cannot be used in standard QO, Homeline, or NQ/NF unit-mount panels.
What does the trailing '1' in the HJA260151 catalog number indicate?
The trailing '1' indicates that this 2-pole breaker is factory-configured for an AB phase connection on the I-Line bus stack.
What does the 'J' in the HJA260151 part number signify?
The 'J' designates the interrupting rating level within the PowerPacT H-Frame series. For this breaker, it provides a high interrupting capacity of 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
What type of load-side terminals are included with the HJA260151?
The breaker comes with standard mechanical lugs on the load side, which accept 14 AWG to 3/0 AWG aluminum or copper wire. The line side utilizes the I-Line plug-on connection.
How does the I-Line connection work on this breaker?
The breaker features plug-on phase jaws that ratchet firmly onto the I-Line bus stack using a single retaining screw. This blow-on connection design eliminates the need to assemble separate connectors to the bus bar, saving installation time.
Can the HJA260151 replace older Square D breakers?
Yes, the PowerPacT H-Frame HJA260151 serves as a modern replacement for legacy 15A, 2-pole I-Line breakers such as the FA26015AB and FH26015AB models.
Is this breaker suitable for DC applications?
Yes, the HJA260151 is rated for use in DC systems up to 250VDC, with an interrupting rating of 20kA at 250VDC.
What type of trip unit does the HJA260151 use?
It uses a thermal-magnetic trip unit with fixed thermal (overload) and fixed magnetic (instantaneous short-circuit) sensing elements. It does not feature an adjustable electronic trip unit.
