Description
Built for residential and commercial applications, the HQS2200H is a 2-pole, 200A molded case circuit breaker from Siemens. It features a plug-on mounting design and thermal-magnetic trip unit for reliable LI protection. Mounts into Siemens Power Mod and Murray meter stacks, serving as a replacement for legacy MDH2200 units. The side-wired design ensures straightforward installation. Rated at an extra-high 100 kAIC at 120/240VAC, this QS frame main breaker safely interrupts severe faults.Specifications

Product FAQs
7 answersWhat equipment is the Siemens HQS2200H compatible with?
This QS frame breaker is designed specifically for use as a tenant main breaker in Siemens Power Mod meter stacks and Murray meter stacks.
How does the HQS2200H QS frame differ from a standard QP breaker?
The HQS2200H is a QS frame breaker built specifically for tenant mains in meter stacks. It features side-entry load lugs and a 100kA interrupting rating. Standard QP breakers are typically used for branch circuits in residential load centers, featuring bottom-entry lugs and lower fault current ratings.
How does the HQS2200H connect within a meter stack?
It features a plug-in connection that snaps directly into the breaker base of the meter stack. The load wires enter the QS breaker from the side, which allows for a single right-hand bend to save time and wire during installation.
Can QS and QP breakers be mixed in the same Siemens Power Mod stack?
Yes, in 225-amp rated Power Mod meter stacks, both QS and QP breakers can plug into the same base. If mixing them in a single stack, Siemens requires the QP breakers to be installed below the QS breakers.
What are the wiring requirements for the HQS2200H load lugs?
The integrated lugs accept copper or aluminum conductors ranging from 3 AWG to 300 kcmil. Always verify that the wire size and insulation rating meet National Electrical Code (NEC) requirements for a 200-amp circuit.
Is the HQS2200H suitable for high fault current applications?
Yes, this breaker provides a 100kA interrupting rating at 240V AC. This high AIC rating makes it ideal for multi-family or commercial metering systems where high available fault current demands robust protection.
Can the Siemens HQS2200H replace older Murray QS breakers?
Yes. Because Siemens acquired Murray, this Siemens-branded QS breaker is the manufacturer-approved replacement for equivalent 200A, 100kAIC Murray QS frame breakers in Murray meter stacks.
