Product FAQs
7 answersCan the Siemens QS2200 replace a discontinued Murray main breaker?
Yes, the Siemens QS2200 serves as a direct, drop-in replacement for the discontinued Murray MD2200 main breaker in legacy Murray load centers.
What is the advantage of the side-wired design on the QS2200?
The exclusive side-wired configuration with right-hand bend wiring allows for clean, efficient cable routing. This design saves wiring space and eliminates difficult S bends during installation.
Which metering enclosures are compatible with the QS2200?
This breaker is designed specifically for use in Siemens Power Mod residential meter stacks and Uni-PAK multi-family metering enclosures.
Does the QS2200 require filler plates when installed in a 100-amp space?
No. The QS frame is designed to fit into the same physical space as standard 100-amp QP breakers, eliminating the need for costly filler plates.
Is the Siemens QS2200 HACR rated?
Yes, this breaker is fully HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.
What is the recommended torque for the wire connections on the QS2200?
The terminal screws should be tightened to a torque of 250 lb-in. Proper torque is crucial for safe and reliable operation to prevent loose connections and overheating.
Can I use Eaton or GE breakers in a Siemens Power Mod meter stack instead of the QS2200?
No. Siemens panels and meter stacks are engineered specifically for Siemens breakers. Using third-party breakers like Eaton or GE can compromise safety, lead to improper functioning, and violate UL listings.
