Product FAQs
7 answersWhat panelboards accept the HQR23B225?
This bolt-on breaker installs directly into Siemens P1, P2, and P3 panelboards, as well as compatible switchboards.
Can the HQR23B225 replace older QJ frame breakers?
Yes. The QR frame is the direct replacement for legacy QJ frame breakers. It shares the same form factor and mounting footprint for easy retrofits in existing enclosures.
What does the H in the HQR23B225 catalog number indicate?
The H designates a high interrupting rating. While standard QR breakers are rated for 10kA at 240V, the HQR series provides a 65kA interrupting capacity at 240VAC.
What wire sizes are accepted by the load side lugs?
The standard lugs accept 3 AWG to 300 kcmil aluminum or copper conductors.
Is the HQR23B225 suitable for reverse feed applications?
Yes. This thermal magnetic breaker features a fixed, non-interchangeable trip unit and is approved for reverse feed wiring configurations.
Does this breaker include a push-to-trip feature?
Yes. The QR frame includes a push-to-trip button on the faceplate for manual mechanical testing of the tripping mechanism.
Are field-installable accessories available for this breaker?
Yes. The QR frame supports internal accessories like shunt trips and auxiliary switches, which can be installed in the field without voiding the UL listing.
