Product FAQs
6 answersWhat types of enclosures are compatible with the CCH2125 circuit breaker?
The Eaton CCH2125 is designed for use in Type ECC unit enclosures and commercial meter stacks, commonly used in multi-tenant service entrance applications.
What is the recommended replacement for the legacy CCH2125 breaker?
For modern panelboard upgrades, the CCH2125 is commonly replaced by the newer CCVH2125 model. Both are CC frame breakers, but you should verify the required interrupting capacity for your specific installation.
What wire sizes are accepted by the terminals on the CCH2125?
The feed-thru lugs accept 2/0 AWG to 300 kcmil conductors. The terminals are rated for both copper and aluminum wiring, making it suitable for standard service entrance feeds.
Can the trip curve be adjusted on the CCH2125?
No. The CCH2125 utilizes a thermal magnetic trip unit with fixed long-time and fixed instantaneous (LI) functions. It does not support field adjustable trip settings.
How does the CCH2125 mount into the panel?
As a bolt-on CC frame breaker, it secures directly to the busbar using bolted connections. Ensure your commercial meter stack or Type ECC enclosure is configured for bolt-on tenant mains.
Is the CCH2125 suitable for use as a tenant main breaker?
Yes, this breaker is frequently utilized as a tenant main in commercial meter stacks and group metering applications to provide essential overcurrent protection for individual units.
