Engineered for metering applications, the Square D QBP22080TM provides reliable 80A overcurrent protection. This 2-pole MCCB features a thermal-magnetic trip unit with fixed LI functions. As a unit mount solution, it installs into Square D EZ Meter-Pak and standard Meter-Pak centers. It also serves as an exact replacement for legacy Q22080 breakers. Rated for 10kAIC at 240VAC, this Q-Frame breaker includes Visi-Trip indication, HACR rating, and stud/tapped pad terminals.
What metering equipment is compatible with the QBP22080TM?
This breaker is engineered specifically for installation in Square D Meter-Pak and EZ Meter-Pak Meter Centers.
How does the stud and tapped pad connection work on this breaker?
The stud and tapped pad design allows the breaker to be bolted directly to the busbars inside the meter center. This provides a secure, high-current connection without the need for standard wire lugs on the line side.
What type of conductors can be used with the load-side terminals?
The load lugs accept either aluminum or copper conductors ranging from 4 AWG to 300 kcmil.
What do the letters "LI" mean in the trip function code?
"LI" stands for Long-Time and Instantaneous. The long-time function protects against sustained overloads, while the instantaneous function trips the breaker immediately during a short circuit.
What does the "TM" suffix in the QBP22080TM catalog number indicate?
The "TM" designates a thermal-magnetic trip unit. It uses a bimetal element for thermal overload protection and an electromagnetic assembly for instantaneous short-circuit protection.
Can I upgrade to a higher interrupting rating if my system requires more than 10kAIC?
Yes. If your fault current study requires a higher rating, you can use other PowerPacT Q-frame breakers. The QDP series offers 25kAIC, the QGP offers 65kAIC, and the QJP provides 100kAIC at 240V.
