Product FAQs
7 answersIs the Siemens QJ22B225H still in production, or is there a direct replacement?
The legacy QJ frame series has been superseded by the newer QR frame series. The direct replacement for the QJ22B225H is the Siemens HQR22B225, which shares the same form factor and mounting but includes updated features like a push-to-trip button.
What types of enclosures are compatible with the QJ22B225H breaker?
This bolt-on breaker is designed exclusively for use in Siemens 240V panelboards and switchboards that accept QJ or QR frame breakers. Always verify compatibility with your specific panel's labeling before installation.
What does the H suffix in the QJ22B225H catalog number indicate?
The H indicates a high interrupting capacity. While standard QJ breakers offer lower fault current protection, the QJ22B225H is rated for 42kAIC at 240VAC, making it suitable for commercial and industrial systems with higher available fault currents.
Can I field-install internal accessories like a shunt trip on the QJ22B225H?
No, internal accessories for legacy QJ frame breakers are factory-installed and cannot be added in the field. If you require field-installable accessories, you must upgrade to the newer QR frame equivalent, the HQR22B225.
Does this breaker support reverse feed applications?
Yes, the QJ22B225H is suitable for reverse feed applications, allowing it to be back-fed when used as a main breaker in compatible panelboards.
Is the QJ22B225H suitable for use with HVAC equipment?
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 overcurrent protection.
Can I install this Siemens QJ breaker in a panelboard from another manufacturer?
No. Installing a Siemens QJ22B225H in a panelboard from a different brand violates the UL listing and can create severe fire hazards due to improper busbar connections. It must only be installed in approved Siemens or legacy ITE enclosures.
