Engineered for commercial and residential distribution, the QS2200HH is a 200A, two-pole miniature circuit breaker providing thermal-magnetic protection for 120/240VAC systems. This plug-on unit mounts into Siemens Power Mod meter stacks and Uni-PAK enclosures. It also serves as a replacement for the discontinued MPD2200KM. Rated at an extra-high 65kAIC, it handles demanding fault currents. The side-wired design saves gutter space and eliminates difficult S-bends during installation.

What equipment is the Siemens QS2200HH compatible with?
This 200A main breaker is designed for use in Siemens Power Mod meter stacks and Uni-PAK multi-family metering enclosures. It mounts directly into the tenant breaker provisions of these systems.
What is the difference between the Siemens QS2200, QS2200H, and QS2200HH?
The primary difference is the interrupting rating. The standard QS2200 is rated at 10kAIC, the QS2200H is rated at 22kAIC, and the QS2200HH is rated for extra-high fault currents at 65kAIC at 240V.
Does the QS2200HH replace any older Siemens or Murray breakers?
Yes, the QS2200HH serves as a direct replacement for the discontinued Murray MPD2200KM circuit breaker previously used in older metering equipment.
How does the side-wired design of the QS2200HH benefit installation?
The exclusive side-wired design saves valuable gutter space in the meter stack and eliminates the need for difficult S-bends when routing large conductors. This single right-hand bend wiring saves both time and wire during installation.
Is the QS2200HH suitable for use as a tenant main breaker?
Yes, this breaker is specifically engineered to serve as a tenant main breaker in multi-family residential and commercial distribution systems, providing thermal-magnetic protection for individual units.
