Used Eaton Cutler-Hammer CH 20 Amp Circuit Breakers

A used Eaton Cutler-Hammer CH 20 Amp circuit breaker can be an economical solution when replacing a breaker in an existing electrical panel. Used breakers may be particularly useful when an older installation requires a specific CH-series breaker that is difficult to find through conventional electrical distribution channels.

Electrical Supplies Unlimited buys and sells used and surplus Eaton and Cutler-Hammer circuit breakers. Availability changes frequently, so contact ESU with the breaker model number or a photograph of the existing breaker and panel label.

Used electrical equipment should be evaluated by a qualified professional before being placed into service. The breaker should be verified for proper compatibility with the panel and electrical system.

Eaton Cutler-Hammer CH 20 Amp Circuit Breaker Replacement

When an Eaton CH 20 amp breaker fails, the correct replacement should match the existing electrical panel and the requirements of the circuit. Simply matching the amperage is not always sufficient. The breaker series, number of poles, voltage rating, interrupting rating, panel compatibility, and breaker features should all be considered.

The Eaton CH120 is specifically designed for Type CH loadcenters. Other 20 amp Eaton breakers, including CHF and CHP models, have different features and applications. Identifying the original catalog number is therefore important when sourcing a replacement.

Electrical Supplies Unlimited specializes in obsolete, discontinued, surplus, and hard-to-find circuit breakers. If you have an older Cutler-Hammer or Eaton panel and cannot locate the original breaker through your normal electrical supplier, ESU may be able to help.

We can search for specific Eaton and Cutler-Hammer models based on the original catalog number, amperage, panel type, and other identifying information. A photograph of the breaker and panel label can also be helpful when identifying older equipment.
