Product FAQs
4 answersWhat is the direct replacement for the Siemens QJ23B080L?
Siemens has replaced the QJ23B080L with the QR23B080L. The QR frame serves as the modern equivalent for this breaker, though the QJ23B080L is still utilized for exact replacements in existing equipment.
Does the QJ23B080L include terminal lugs?
Yes, this feed-thru breaker includes factory-installed line and load lugs. They are dual-rated for copper (6 AWG to 300 kcmil) and aluminum (4 AWG to 300 kcmil) conductors.
Is the QJ23B080L compatible with standard residential load centers?
No. This is a unit-mount breaker designed for individual mounting, meter centers, and specific enclosures. It does not mount directly to standard load center bus bars.
Are the trip settings adjustable on the QJ23B080L?
No. This breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. The trip points cannot be modified in the field.
