Product FAQs

5 answers
What enclosures are compatible with the QCC2125 breaker?

The QCC2125 is designed specifically for use in legacy Eaton meter stacks and Type ECC unit enclosures, typically functioning as a tenant main breaker.

Is there a modern replacement for the legacy QCC2125 circuit breaker?

Yes, the QCC2125 is a legacy unit that has been officially replaced by the Eaton CCV2125. The CCV2125 serves as a direct replacement for tenant main applications in compatible meter stacks.

How does the QCC2125 connect within the meter stack?

This breaker features a feed-thru connection and installs via unit mounting. It includes line and load lugs that accept 2/0 AWG to 300 kcmil copper or aluminum wire.

What type of trip unit does the QCC2125 utilize?

It uses a fixed thermal-magnetic trip unit, providing both long-time overload protection and instantaneous short-circuit protection.

Can I use the QCC2125 to replace older Cutler-Hammer or Westinghouse QCC breakers?

Yes. Because Eaton absorbed the Cutler-Hammer and Westinghouse product lines, the QCC2125 is an exact replacement for legacy breakers sharing the same QCC frame and catalog number.
