Product FAQs
6 answersDoes the QRH23B225 replace older QJ frame circuit breakers?
Yes. The Siemens QR frame is the direct successor to the legacy QJ frame. The QRH23B225 serves as a drop-in replacement for older QJ23B225 and QJH23B225 breakers, fitting the same panelboard spaces.
What is the difference between the QR23B225 and the QRH23B225?
The difference is the interrupting rating. The standard QR23B225 is rated for 10kA at 240V, while the QRH23B225 features a high interrupting capacity of 25kA at 240V. Always verify the available fault current at your installation point to ensure the correct rating is selected.
What is the recommended tightening torque for the load side lugs on this breaker?
For the standard aluminum lugs accepting 2/0 AWG to 300 kcmil wire, the required tightening torque is 225 in-lb (25.4 N-m). If using smaller wire sizes like #3 to 1/0 AWG, the torque specification is 100 in-lb (11.3 N-m).
Which Siemens panelboards are compatible with this QR frame breaker?
This bolt-on molded case circuit breaker is designed specifically for integration into Siemens P2, P3, P4, and P5 panelboards, as well as SB switchboards. It is not intended for standard residential load centers.
What temperature rating is required for the conductors connected to this 225A breaker?
For circuit breakers with a rated ampacity greater than 125A, industry standards require the use of 75 degree Celsius rated conductors. Ensure all connected cables meet this requirement and are properly derated according to the National Electrical Code.
Is this breaker suitable for reverse feed applications?
Yes. The QRH23B225 is UL listed for reverse feed applications, allowing it to be back-fed when used as a main breaker in compatible panelboards.
