CH120 - 20Amp Circuit Breaker

CH120 20 Amp 1-Pole Type CH Circuit Breaker

The CH120 is a 20 Amp, 1-pole Type CH circuit breaker designed for use in compatible CH load centers and panelboards. For many replacement projects, finding the correct breaker means matching more than just the amp rating. The breaker type, mounting style, and panel compatibility all matter. The CH120 is intended for applications that require a Type CH plug-on breaker and is commonly used on 120-volt branch circuits in residential and commercial electrical systems.

Whether you're replacing a breaker during routine maintenance or working on an existing panel, using the correct component helps preserve the original design of the equipment.

Many electrical panels remain in service for years, and replacement parts need to match the equipment they are being installed into. The CH120 was built for that purpose, providing the form, fit, and function required for compatible CH systems. Built to last, it continues to be a practical option for maintaining existing electrical distribution equipment.
