20 Amp 1 Pole Standard CHF Circuit Breaker · Eaton CHF120
What this product is for
The Eaton CHF120 is a Type CH single-pole thermal-magnetic circuit breaker used to protect 120/240V branch circuits from overloads and short circuits in compatible Eaton CH loadcentres and panelboards.
Use for
Use for residential and light commercial panel applications requiring a 20A, 1-pole breaker with 10 kAIC interrupting capacity. Suitable where a trip flag helps identify a tripped breaker faster during service calls.
Avoid for
Avoid using this breaker in non-CH panels, in applications requiring AFCI, GFCI, or dual-function protection, or where a different pole count, amp rating, or interrupting rating is specified.
Best for
Best for electricians matching an existing Eaton Type CH panel and needing a standard 3/4 in (19.1 mm) wide breaker footprint with visual trip indication.
Installed in
Installed in Eaton Type CH loadcentres and panelboards. Typical branch circuit use may include receptacle, lighting, or dedicated equipment circuits where a 20A single-pole breaker is specified.
Why this product exists
This breaker provides branch circuit protection in a compact Type CH format while adding a trip flag for easier troubleshooting. For buying guidance, a common rule of thumb is that continuous load should not exceed 80% of breaker rating, or approximately 16A on a 20A breaker. Actual allowable loading depends on code, conductor sizing, ambient conditions, and the connected equipment.
Compared with similar products
Compared with specialty CH breakers, the CHF120 is a standard thermal-magnetic breaker rather than an AFCI, GFCI, or dual-function model. It is intended for standard overcurrent protection where code does not require additional fault protection.
