Product FAQs
7 answersDoes the QJ22B090L include both line and load lugs?
Yes. The L at the end of the QJ22B090L catalog number indicates that the breaker is supplied with both line and load side lugs factory-installed. Standard QJ breakers without the L suffix typically only include load side lugs.
What equipment is the QJ22B090L designed to fit?
This unit-mount breaker is designed for installation in compatible Siemens enclosures, switchboards, and meter centers that accept QJ-frame breakers. It is a feed-thru breaker and does not plug or bolt directly onto a standard panelboard bus.
Can the QJ22B090L be reverse fed?
Yes, this breaker is reverse-feed capable. It can be wired with the supply power connected to either the top or bottom terminals, which is useful in certain meter center and enclosure configurations.
Are the trip settings on the QJ22B090L adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and non-adjustable.
What is the difference between the QJ22B090 and the QJ22B090L?
The base QJ22B090 typically comes with load-side lugs only, intended for applications where the line side connects directly to a bus. The QJ22B090L includes both line and load lugs for feed-thru, unit-mount applications.
Is the QJ22B090L HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific level of circuit protection.
Has the Siemens QJ frame been discontinued?
The QJ frame is a legacy series that has largely been replaced by the newer QR frame for modern applications. However, exact QJ replacements like the QJ22B090L are often required to maintain compatibility in existing panels and meter centers.
