Product FAQs
7 answersWhat load centers are compatible with the Q115HH?
The Q115HH is designed for use in Siemens load centers that accept QP type plug-on breakers, including EQ, Ultimate, PL, ES, and PN series panels.
What does the HH in the Q115HH part number indicate?
The HH suffix designates an extra-high interrupting rating of 65kAIC at 120V. This exceeds the ratings of standard Q115 (10kAIC) and Q115H (22kAIC) breakers in the QP family.
Is the Siemens Q115HH HACR rated?
Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific safety designation.
Can this breaker be used for switching fluorescent lighting?
Yes, the Q115HH is SWD (Switching Duty) rated. This means it is approved for switching 120V fluorescent lighting circuits on and off on a regular basis.
Does the Q115HH require a plug-on neutral connection?
No. The Q115HH is a standard thermal-magnetic breaker, not an AFCI or GFCI device. It does not require a plug-on neutral or a neutral pigtail connection.
Can the Q115HH replace a standard Q115 or Q115H breaker?
Yes. Because it shares the exact same physical footprint and trip characteristics, the Q115HH can replace a Q115 or Q115H breaker, providing a higher interrupting capacity for the circuit.
Will this breaker fit in older Murray load centers?
Siemens has phased out the Murray brand and issued a substitution letter authorizing the use of Siemens QP breakers, including the Q115HH, in Murray Rock Solid load centers. Always verify compliance with your local inspector.
