The factory-installed lugs accept 6 AWG to 300 kcmil copper wire, or 4 AWG to 300 kcmil aluminum wire.
Are the trip settings on this breaker adjustable?
No, the QJH22B150 features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
Can the QJH22B150 be used in reverse feed applications?
Yes, this QJ-frame breaker is reverse feed capable, allowing it to be back-fed in compatible panelboard and switchboard configurations.
What is the modern replacement for the QJH22B150?
Siemens has transitioned the QJ frame to the newer QR frame. The QRH22B150 serves as the modern equivalent, though a specific mounting kit may be required when retrofitting into older panels.
