CH120 **Old Style Half Notch** - 20Amp Circuit Breaker

CH120 **Old Style Half Notch** - 20Amp Circuit Breaker

The CH120 Old Style Half Notch is a 20 Amp, 1-pole Type CH circuit breaker used in compatible CH load centers and panelboards that require the older-style half notch configuration. When you're replacing a breaker in an existing panel, matching the physical style is often just as important as matching the amperage. This breaker is intended for installations where a standard CH breaker is not enough and the original half notch design must be maintained.

Rated for 120 VAC applications with a 10kA interrupting capacity, the CH120 is commonly used on general-purpose branch circuits in residential and light commercial electrical systems.

Older electrical panels can remain in service for many years when properly maintained, but replacement parts still need to match the equipment they are being installed into. That's where the CH120 Old Style Half Notch comes in. It provides the form, fit, and function needed for compatible applications while helping preserve the original configuration of the electrical system.
