Product FAQs
5 answersCan I install the Siemens Q115H in a Murray load center?
Yes. Siemens acquired Murray and officially phased out the brand in 2019. Siemens issued a substitution letter confirming that Type QP and QPH breakers are UL-listed for use in Murray load centers.
What does the H stand for in the Q115H catalog number?
The H indicates a high interrupting rating. While a standard Siemens Q115 has a 10kAIC rating, the Q115H is rated for 22kAIC at 120V, making it suitable for systems with higher available fault current.
Is the Q115H circuit breaker HACR and SWD rated?
Yes, the Siemens Q115H is HACR rated for use with heating, air conditioning, and refrigeration equipment. It is also SWD (Switching Duty) rated, meaning it is approved for switching 120V fluorescent lighting loads on a regular basis.
Does the Q115H replace the Murray MP115H?
Yes. Siemens Type QPH breakers are the direct, UL-listed replacements for legacy Murray Type MP-HT breakers, including the 15-amp MP115H.
Does the Q115H provide AFCI or GFCI protection?
No, the Q115H is a standard thermal-magnetic circuit breaker. It does not provide arc-fault (AFCI) or ground-fault (GFCI) protection.
