Description
Designed for maximum fault handling, the Eaton CHH2225 offers 225A of thermal-magnetic protection. It operates as a high-capacity tenant main for demanding residential and commercial service drops. This breaker mounts into Eaton 1MP and 1MM modular metering stacks. For future upgrades, it is replaced by the CVH2225XMM model. Boasting an exceptional 100 kAIC rating at 240V, it safely clears severe short circuits. The breaker includes line and load lugs and carries an HACR rating.Specifications

Product FAQs
5 answersWhat equipment is the CHH2225 designed to be installed in?
This breaker is primarily used as a tenant main breaker in Eaton 1MP, 1MM, and 3MM modular metering stacks.
What wire sizes are accepted by the lugs on this breaker?
The line and load side lugs on the CHH2225 accept #2 AWG through 300 kcmil copper or aluminum conductors.
Is there a direct replacement for the legacy CHH2225 breaker?
Yes, the Eaton CVH2225XMM serves as a direct replacement for the discontinued CHH2225. It maintains the same 100kAIC interrupting rating and includes the necessary mounting kit for metering stacks.
What does the CHH frame designation indicate compared to standard CH breakers?
The CHH designation indicates a high interrupting capacity. While standard CH breakers typically have a 10kAIC rating, the CHH2225 is rated for 100kAIC at 240V, making it suitable for applications requiring higher fault current protection.
Does this breaker require a separate mounting kit for installation in metering stacks?
As a legacy bolt-on breaker, the CHH2225 is designed to bolt directly into compatible Eaton 1MP, 1MM, and 3MM modular metering stacks without requiring an additional adapter kit.
