Product FAQs
5 answersWhat metering equipment is compatible with the Siemens QS2175?
This 175A main breaker is designed specifically for installation in Siemens Power Mod meter stacks and Uni-PAK metering enclosures.
What is the direct replacement for the obsolete Murray MPD2175?
The Siemens QS2175 serves as the exact, drop-in replacement for the discontinued Murray MPD2175 main breaker.
Does the QS2175 require filler plates during installation?
No. The QS frame utilizes an exclusive side-wired design with right-hand bend wiring, allowing it to fit cleanly into compatible meter stacks without the need for filler plates.
How does the side-wired design of the QS frame benefit panel builders?
The side-wired configuration eliminates the need for S-bends in the conductors. This simplifies cable routing and saves valuable time during meter stack assembly.
What are the higher AIC alternatives to the standard QS2175?
The QS2175 provides 10kAIC protection. For applications requiring higher fault current ratings, alternatives include the QSH2175 at 22kAIC, QS2175HH at 42kAIC, and HQS2175H at 100kAIC.
