The QJA32080 is a reliable Square D 3-pole circuit breaker, designed for superior performance in residential and commercial applications. With an 80A rating and 240V capacity, this I-Line breaker ensures optimal protection against overloads and short circuits. Count on its durability and efficiency for your electrical systems.
The QJA32080 uses Square D's I-Line plug-in bus connection, making it compatible with Square D I-Line panelboards and switchboards (such as NF and NQ series). It is not interchangeable with QO or Homeline residential loadcentres. Contact us with your panel model and we'll confirm fitment.
The QJA frame has been largely superseded by newer Square D MCCB lines. If your exact application requires the QJA32080, Northern Breaker Group specializes in sourcing hard-to-find and obsolete breakers — reach out to our team and we can check current stock or source availability.
The QJA32080 can serve as either a main or branch circuit breaker depending on your panelboard's configuration and the application's design requirements. With its 100kA interrupting rating at 240V, it is well-suited for demanding commercial or industrial distribution. Always verify with your panelboard's documentation and a qualified electrician to ensure compliance with local electrical codes.
