Product FAQs

What equipment is the CC2125 designed to be installed in?
This breaker functions as a tenant main and is designed to mount into Eaton 1MP, 1MM, and 3MM modular meter stacks, as well as Type ECC unit enclosures.
Is there a direct replacement for the legacy CC2125 breaker?
Yes, the CC2125 has been replaced by the newer Eaton CCV2125 model. While both are 125A, 2-pole tenant main breakers with a 10kAIC rating, note that the CCV2125 accepts larger 2/0 AWG to 300 kcmil wiring compared to the 4 AWG to 4/0 AWG capacity of the original CC2125.
How does a feed-thru connection work on the CC2125?
A feed-thru configuration means the breaker features standard lugs on both the line and load sides. This allows conductors to be wired directly to both ends instead of plugging or bolting onto a panel busbar.
