Built to handle higher fault currents, the Siemens QS2200H delivers 200 amps of protection with a 22kAIC rating at 120/240VAC. This two-pole plug-on main breaker is specifically manufactured for Siemens Power Mod meter stacks and Uni-PAK metering systems. The convenient side-wired design and right-hand bend wiring streamline the installation process while eliminating the need for filler plates. It also serves as an exact substitute for the legacy Murray MDH2200 main circuit breaker.

Which metering systems and panels accept the QS2200H?
This breaker is specifically designed for Siemens Power Mod Meter Stacks, Uni-PAK Metering systems, and legacy Murray load centers.
Can the Siemens QS2200H replace older Murray main breakers?
Yes, the QS2200H serves as a direct replacement for the discontinued Murray MDH2200 main circuit breaker in legacy Murray load centers.
What is the difference between the Siemens QS2200 and the QS2200H?
The H in the catalog number designates a high interrupting capacity. The standard QS2200 is rated for 10kAIC at 240V, while the QS2200H is built to handle higher fault currents with a 22kAIC rating.
Does the QS2200H require filler plates when installed in a meter stack?
No, this breaker features a side-wired design and right-hand bend wiring that allows for clean cable routing without the need for filler plates.
Is the QS2200H designed for use as a main or branch breaker?
The QS2200H is engineered to function as a main breaker disconnect in multi-family metering enclosures and compatible residential load centers.
