Product FAQs
7 answersCan I use the QRH22B225L to replace older QJ frame breakers?
Yes, the QRH22B225L functions as a direct replacement for discontinued Siemens QJ frame breakers, including the QJ22B225 and QJH22B225. It provides the same 225A rating and 2-pole configuration while upgrading to the modern QR frame.
What is the difference between the QR22B225L and the QRH22B225L?
The H in the QRH22B225L part number indicates a higher interrupting rating. While the standard QR22B225L is rated for 10kAIC at 240V, the QRH22B225L provides 25kAIC for systems with elevated fault currents.
Is the QRH22B225L approved for reverse feed applications?
Yes, this breaker is approved for reverse feed applications, allowing it to be back-fed when installed in compatible panelboards or enclosures.
Is this circuit breaker HACR rated?
Yes, the Siemens QRH22B225L is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment.
What wire sizes are compatible with the lugs on this breaker?
The included line and load side lugs accept aluminum or copper wire ranging from 4/0 AWG to 300 kcmil.
How does the QRH22B225L mount into an electrical system?
This is a unit-mount, feed-thru circuit breaker. It bolts into place and is designed for use in individual Siemens enclosures or standalone mounting rather than plugging directly into a load center bus.
Are the trip settings on the QRH22B225L adjustable?
No, this breaker features a non-interchangeable thermal magnetic trip unit with fixed long time and instantaneous functions.
