Product FAQs
6 answersWhat equipment is the QS2150HH compatible with?
It is designed for use in Siemens Power Mod Meter Stacks, including WMM and WML types, as well as Uni-PAK multi-family metering systems.
What is the difference between the QS2150, QS2150H, and QS2150HH?
The suffix indicates the short circuit interrupting rating at 240V. The standard QS2150 is rated at 10kAIC, the QS2150H is rated at 22kAIC, and the QS2150HH provides the highest rating at 65kAIC. All three share the same 150A, 2-pole QS frame.
What are the torque specifications for the QS2150HH lugs?
For 3 AWG to 300 kcmil copper or aluminum wire, torque the terminal screws to 250 lb-in. Always use a calibrated torque wrench to prevent loose connections and overheating.
Can I mix QS and QP breakers in the same Siemens meter stack?
Yes, in 225A rated meter stacks, both QS and QP breakers plug into the same bases. If mixing them in one stack, Siemens requires installing the QP breakers below the QS breakers.
How is the QS2150HH wired in a meter stack?
The QS frame features a side-wired design. This allows for a single right-hand bend, which saves time and wire during installation in multi-tenant meter stacks.
What temperature rating is required for the conductors used with this breaker?
The QS2150HH is designed for use with 75 degree Celsius rated copper or aluminum wire.
