Description
Engineered for commercial and industrial environments, the Siemens Q360H delivers robust thermal-magnetic protection. This 3-pole, 60-amp component features a 22kAIC rating at 240VAC to handle higher fault currents than standard residential models. It installs into Siemens load centers and P1 panelboards, utilizing a standard plug-on mounting style. Facility managers can also utilize this unit as a verified drop-in replacement for legacy MP360H and QPH360 breakers.Specifications

Product FAQs
7 answersWhat is the difference between the Siemens Q360 and Q360H?
The standard Q360 has an interrupting capacity of 10kAIC, while the Q360H features a higher interrupting rating of 22kAIC at 240VAC to safely clear higher available fault currents.
Which panels are compatible with the Q360H circuit breaker?
The Q360H is designed for plug-on installation in Siemens load centers and panelboards that accept Type QP or QPH miniature circuit breakers.
Can the Q360H replace older Murray circuit breakers?
Yes, the Q360H is a verified drop-in replacement for legacy Murray MP360H breakers, as well as older Siemens or ITE QPH360 models.
Is the Siemens Q360H HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection profile.
Does the Q360H provide ground-fault or arc-fault protection?
No, the Q360H is a standard thermal-magnetic circuit breaker. It provides overload and short-circuit protection but does not include GFCI or AFCI circuitry.
Can the Q360H be installed in 480V systems?
No, the Q360H is strictly rated for a maximum of 240VAC. It is not suitable for 277V or 480V applications.
What wire types and sizes are accepted by the Q360H lugs?
The breaker terminals are rated for both copper (Cu) and aluminum (Al) conductors, accepting wire gauges from 6 AWG to 3 AWG. Always verify the required torque specifications printed directly on the breaker before terminating.
