Product FAQs
6 answersWhat is the modern replacement for the legacy MPD2175?
The Siemens QN2175 is the direct drop-in replacement for the legacy MPD2175. Both breakers share the same physical footprint, making the QN2175 a standard substitute for panel upgrades.
How many panel spaces are required to install this main breaker?
The MPD2175 requires four full panel spaces for proper mounting in a compatible load center or meter combination.
Can I install this breaker in an older Murray panel?
Yes. Siemens acquired Murray, and this breaker is fully compatible with legacy Murray load centers that are designed to accept MPD frame main breakers.
Is the MPD2175 HACR rated?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment circuits.
Does this 2-pole breaker feature a common trip mechanism?
Yes, it features an internal common trip mechanism. An overload or short circuit on one pole will simultaneously trip both poles to safely disconnect power.
What is the ambient operating temperature rating for this breaker?
The MPD2175 is calibrated for a standard ambient operating temperature of 40 degrees Celsius (104 degrees Fahrenheit).
