Engineered for specific panel configurations, the Siemens MPD2175R is a 175A, two-pole main breaker. It features a reverse handle design where the ON position faces the lugs, accommodating unique installations. It installs into compatible Siemens and legacy Murray load centers using a plug-on connection. For newer panelboard systems, it is replaced by the QN2175R model. This unit provides reliable 10 kAIC protection at 120/240VAC with fixed thermal-magnetic trip functions.

Product FAQs
3 answers
What does the "R" in the MPD2175R catalog number indicate?
The "R" signifies a reverse handle design. In this configuration, the ON position faces the terminal lugs, which is required to accommodate specific main breaker panel orientations.
Can the Siemens MPD2175R be installed in legacy Murray load centers?
Yes. Since Siemens acquired Murray, this breaker serves as the direct, manufacturer-approved replacement for older Murray MD-T and MPD series 175A main breakers.
What is the difference between the MPD2175R and the QN2175R?
The MPD2175R is the exact replacement for older MD-T frame installations. The QN2175R is the newer double-frame style used in modern Siemens panelboards. Electricians must use the specific frame type that matches the load center busbar.
