Product FAQs
7 answersWhat meter stacks are compatible with the CVH2150XMM?
This tenant main breaker is designed specifically for group metering applications. It mounts directly into Eaton 1MM, 3MM, and 1MP residential modular meter stacks.
What does the XMM suffix indicate on this Eaton breaker?
The X indicates that the load terminals accept up to 4/0 AWG wire. The MM suffix signifies that the breaker includes the 1MMCBK mounting hardware kit required for installation in 200A modular metering stacks.
Can the CVH2150XMM replace older Cutler-Hammer tenant breakers?
Yes, this breaker serves as a functional drop-in replacement for legacy Cutler-Hammer CHH2150 tenant main breakers in existing multi-metering installations.
How does the CVH2150XMM differ from the CV2150 and CVS2150?
While these models share the same physical CV frame and 150A rating, they feature different short-circuit interrupting capacities. The CVS is rated at 42kAIC, the standard CV is rated at 65kAIC, and the CVH provides the maximum 100kAIC rating for systems with high available fault currents.
Do I need to purchase a separate mounting kit to install this breaker?
No. The required mounting hardware for securing the breaker to the meter stack bus is included with this specific XMM catalog number. If you were using a standard CVH2150, you would need to order the 1MMCBK kit separately.
What wire sizes are accepted by the load terminals?
The factory-installed load lugs accept copper or aluminum conductors ranging from 6 AWG up to 4/0 AWG. Always torque the terminal screws to the specifications printed directly on the breaker label.
Does this breaker provide ground fault or arc fault protection?
No. The CVH2150XMM is a standard thermal magnetic circuit breaker designed to provide overload and short-circuit protection. It does not include GFCI or AFCI circuitry.
