CH120 **Old Style Full Notch** - 20Amp Circuit Breaker Description
CH120 **Old Style Full Notch** - 20 Amp Circuit Breaker
The CH120 Old Style Full Notch circuit breaker is a 1-pole, 20-amp plug-on breaker designed for use in CH-type load centers requiring the older style full notch configuration. Rated at 10kA A.I.C. at 120VAC, this breaker provides dependable overcurrent protection for branch circuits in residential and light commercial electrical systems. Built for proper form, fit, and function, it is specifically suited for panels that require the full notch design, ensuring correct seating and secure connection within compatible CH load centers. With its compact footprint and straightforward installation, the CH120 helps maintain the integrity and safety of existing electrical distribution systems that rely on legacy CH-style components.
Engineered to meet applicable industry standards for thermal-magnetic circuit protection, this breaker is built to last and designed to interrupt overloads and short circuits within its rated capacity. If you are maintaining or servicing an older CH panel that requires a full notch breaker, the CH120 offers the compatibility and ratings necessary to keep your system operating as intended.
Key Features and Benefits
- 20 Amp Single-Pole Protection – Designed to protect individual 120V branch circuits from overloads and short circuits.
