Product FAQs
5 answersWhat panels accept the Siemens Q360HH breaker?
It is designed for use in Siemens P1 Panelboards and Siemens 3-Phase Load Centers that accept Type QP plug-on breakers.
Can the Q360HH replace older Murray breakers?
Yes. Siemens acquired Murray and phased out the brand. The Siemens Type QP series, including the Q360HH, is the officially UL-listed direct replacement for legacy Murray Type MP breakers, such as the MP360HH, in panels manufactured after January 2002.
What does the "HH" in the Q360HH catalog number indicate?
The "HH" suffix designates a high interrupting rating of 65kAIC at 240VAC. For comparison, standard Q360 breakers are rated at 10kAIC, and Q360H models are rated at 22kAIC.
What is the recommended lug torque for the Q360HH breaker?
For the supported 6-4 AWG copper or aluminum conductors, the standard torque specification for Siemens QP breaker lugs is 45 lb-in. Always verify the exact torque requirements printed on the breaker label prior to installation.
Is the Siemens Q360HH HACR rated?
Yes, this thermal-magnetic breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
