Built for heavy-duty applications, the Square D QGA32080 is an 80A, 3-pole molded case circuit breaker from the PowerPacT Q series. It delivers consistent performance for commercial and industrial power distribution networks. Designed for seamless integration, it installs into Square D I-Line panelboards (HCN, HCM, HCW, HCWM) and switchboards. It is also a direct substitute for the older Q23080 model. This 80% rated breaker offers a 65kAIC rating at 240VAC and fixed thermal-magnetic trip.
What panelboards are compatible with the QGA32080 circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards, including the HCN, HCM, HCW, and HCWM series, as well as I-Line switchboards.
How does the QGA32080 connect to the electrical panel?
It utilizes an I-Line plug-on connection for the line side, which snaps directly onto the panel bus, and features mechanical lugs on the load side for wire terminations.
What is the recommended lug torque for the load side terminals?
The load side mechanical lugs should be torqued to 248 lb-in (28 N.m) when using 4 AWG to 300 kcmil aluminum or copper conductors.
