Product FAQs

5 answers
Where is the CAH2125 typically installed?

This 125A C-Frame breaker is commonly used as a tenant main breaker in multi-tenant power distribution. It is compatible with Eaton and Cutler-Hammer group metering stacks as well as Type ECC enclosures.

Are line and load lugs included with the CAH2125?

Yes, standard line and load lugs are included. They accommodate wire sizes ranging from #6 AWG to 350 kcmil.

Does the CAH2125 plug onto a busbar?

No. The CAH2125 is a unit mount, feed-thru circuit breaker. It mounts directly into compatible metering stacks or ECC enclosures rather than snapping or plugging onto a standard panel busbar.

Are the trip settings on the CAH2125 adjustable?

No, the thermal-magnetic trip unit is fixed. Both the long-time (overload) and instantaneous (short circuit) trip functions are factory set and cannot be adjusted in the field.

Can I use an Eaton CAH2125 to replace an older Cutler-Hammer CAH2125?

Yes. Eaton acquired Cutler-Hammer, and they manufacture the exact same C-Frame breakers under the Eaton name. The CAH2125 is a direct, drop-in replacement for older Cutler-Hammer models with the same catalog number.
