Description
Engineered for residential and commercial applications, this 110-amp QP series component provides reliable thermal-magnetic protection. It installs into standard Siemens load centers and panelboards requiring a two-pole footprint. Featuring a 22kAIC high interrupting capacity, it handles demanding fault currents while serving as an exact, code-compliant substitute for legacy Murray MP2110H installations. The unit includes common trip functionality and carries an HACR rating for HVAC equipment.Specifications

Product FAQs
6 answersCan I use the Siemens Q2110H in a panel that specifies Type QP breakers?
Yes. The Q2110H is a Type QPH breaker, which shares the exact physical dimensions and plug-in mounting style as standard Type QP breakers. The H designation indicates a higher interrupting rating of 22kAIC. It can be installed in Siemens load centers that accept QP breakers.
What is the difference between the Siemens Q2110 and the Q2110H?
The difference is the maximum interrupting capacity. The standard Q2110 has a 10kAIC rating, while the Q2110H features a high interrupting capacity of 22kAIC at 240V. You can safely replace a Q2110 with a Q2110H, but you cannot use a standard Q2110 if your system fault current calculation requires a 22kAIC rating.
Is the Q2110H a direct replacement for the Murray MP2110H?
Yes. Siemens manufactures both product lines, and the Q2110H serves as an exact, code-compliant substitute for legacy Murray MP2110H plug-in circuit breakers.
Does the Q2110H use a plug-on or bolt-on mounting connection?
The Q2110H is a plug-on circuit breaker designed for standard Siemens load centers. If your commercial panelboard requires a bolt-on connection, this plug-in breaker will not fit.
How much panel space does the Q2110H require?
As a 2-pole Type QPH breaker, it requires two standard 1-inch spaces in a compatible Siemens load center or panelboard.
Is the Siemens Q2110H rated for HVAC equipment?
Yes, this breaker carries an HACR rating, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 110-amp, 2-pole overcurrent protection device.
