Product FAQs
5 answers
What is the difference between the Eaton CCVH2125 and the CCV2125?
Both are 125A, 2-pole tenant main breakers with an identical physical footprint. The difference is their short-circuit interrupting capacity. The standard CCV2125 is rated at 10 kAIC, while the CCVH2125 is the high-interrupting version rated for 25 kAIC at 120/240V.
Which metering stacks and enclosures accept the CCVH2125?
This tenant main breaker is engineered for multi-family and commercial group metering. It installs directly into Eaton 1MP, 1MM, and 3MM modular metering stacks, as well as Type ECC unit enclosures used for service entrance equipment.
Can the CCVH2125 replace an older CCH2125 breaker?
Yes. The modern CCVH frame retains the exact same profile and footprint as the legacy CCH frame. This makes the CCVH2125 a direct, backward-compatible replacement for the obsolete CCH2125 in existing metering stacks.
What is the difference between the CCVH2125 and the CCVH2125X?
The standard CCVH2125 includes both line and load side lugs installed from the factory. A catalog number with an X suffix, such as CCVH2125X, indicates that the breaker is supplied with load side lugs only.
Are the lugs on this breaker rated for aluminum wire?
Yes, the factory-installed line and load lugs are dual-rated for both copper and aluminum conductors. They accept wire sizes ranging from 2/0 AWG to 300 kcmil.
