Eaton 66C1478G10 Circuit Breaker

The Eaton 66C1478G10 is a CH-series, single-pole circuit breaker engineered for 120V circuits, combining compact form-factor with Eaton's established reliability to protect a dedicated branch from electrical faults. With a 20-amp rating, it interrupts current when the load or fault exceeds safe levels, helping prevent overheating, wiring damage, and broader electrical issues in panels that accept CH-type breakers. The device is identified by the part number 66C1478G10 and carries the CAF GF designation, which confirms its precise fit within Eaton's CH family and supports consistent performance when replacing an existing breaker in compatible installations. As a 1-pole breaker, it safeguards a single hot conductor of a 120V circuit, making it suitable for typical residential lighting or receptacle circuits wired for 120V and used in appropriate Eaton panel configurations. This exact specification helps ensure correct replacement in field service or new installations where a CH-type, 1-pole, 20A, 120V breaker is required.
