Product FAQs
5 answersDoes the QR23B100L replace older Siemens QJ frame breakers?
Yes, the QR23B100L is a direct replacement for the discontinued QJ23B100L circuit breaker. The QR frame shares the same physical footprint and mounting configuration as the legacy QJ frame for straightforward retrofitting.
What does the L suffix in the QR23B100L catalog number indicate?
The L suffix indicates that the circuit breaker comes factory-installed with both line and load side lugs. Standard QR breakers without this suffix are typically supplied with load side lugs only.

The QR23B100L can be housed in dedicated Siemens QR Series enclosures. Compatible models include the QR2N1S for NEMA 1 indoor applications, the QR2N3R3 for NEMA 3R outdoor use, and the QR2N4X for NEMA 4X watertight protection.
Is the Siemens QR23B100L suitable for reverse feed applications?
Yes, this molded case circuit breaker is rated for reverse feed installations. This allows it to be back-fed when used as a main breaker in compatible panels or switchboards.
Is this circuit breaker HACR rated?
Yes, the QR23B100L carries an HACR rating, meaning it is tested and approved for the specific electrical demands of heating, air conditioning, and refrigeration equipment.
