Eaton CHF120 – Frequently Asked Questions

1) Will an Eaton CHF breaker fit a Type CH loadcenter panel?
The CHF Series is built for Eaton Type CH loadcenters and plugs onto the CH bus. It's a single-pole, 3/4-inch standard-width breaker, so it takes one full 3/4-inch pole space in the panel. It is not a CL or BR breaker and won't work in a BR-bus panel; check the label inside your panel door for CH before ordering.
2) Can I use an Eaton CHF single-pole breaker on an air conditioner or heat pump circuit?
Yes, the CHF is HACR rated, which is the marking an inspector looks for on a breaker feeding heating, air conditioning, and refrigeration equipment with motor loads. Sizing follows the nameplate on the unit. Note it is single-pole at 120/240V, so a 240V condenser needing two poles takes a two-pole breaker, not this one.
3) What wire size can I land on an Eaton CHF breaker?
The CHF terminal takes (2) #14-10 AWG copper or aluminum. That's a dual-rated lug, so aluminum branch conductors are permitted, and it will accept two conductors under the screw where the Code allows it. Above 10 AWG (for example a 50A circuit on 6 AWG) this terminal is out of range, so confirm the conductor size your circuit needs before you pick the amperage.
4) When should I order the shunt-trip CHF instead of the standard breaker?
Order shunt-trip when something outside the panel has to open the breaker remotely: an elevator recall on a sprinkler flow switch, a kitchen hood suppression system dropping the appliance circuit, or an emergency shutdown pushbutton. A standard CHF only trips on its own overcurrent. Shunt-trip needs a control conductor run to it and a source to energize the coil, so plan that wiring into the job. Available at 15A (CHF115ST), 20A, and 50A (CHF150ST).
5) Can I replace an existing CH breaker in my panel with a CHF?
Yes. The CHF shares the Type CH plug-on interface and the 3/4-inch single-pole footprint, so it drops into the same space a CH single-pole occupies, matched amperage for amperage. Terminals take (2) #14-10 AWG Cu/Al, so the existing branch conductor lands the same way. What changes is that you gain the trip flag.
6) What is the difference between an Eaton CHF and a plain CH breaker?
The F in CHF is the trip flag. A CHF carries visual trip indication so you can see at a glance which breaker opened instead of cycling every handle to find it. Electrically it's the same footprint as a standard CH single-pole: 120/240V, 10 kAIC, 3/4-inch space, on the Type CH bus. On a building with a lot of nuisance trips or a maintenance crew troubleshooting after hours, the flag is what you're paying for.
7) What amperages does the Eaton CHF single-pole breaker come in?
Four: 15A, 20A, 30A, and 50A. Fifteen and twenty cover general lighting and receptacle branch circuits, thirty is the usual water heater or small appliance circuit, and fifty is the top of this single-pole range. Catalog numbers run CHF115, CHF120, CHF130, and CHF150.
8) What is the red handle version of the Eaton CHF breaker for?
The red handle is the fire-alarm designation. It marks the breaker feeding the fire alarm control panel so nobody kills that circuit during service, and many AHJs want that circuit identified and lockable. It's offered at 15A (CHF115F), 20A (CHF120F), and 50A. Everything else about the breaker is unchanged: single-pole, 120/240V, 10 kAIC, Type CH bus.
9) Is the Eaton CHF breaker UL listed for use in a commercial building?
UL 489 listed, the standard for molded case circuit breakers, and HACR rated for motor loads. Voltage rating is 120/240V, which suits single-phase residential and light commercial loadcenters. It is not a GFCI or AFCI device, so where the Code requires ground-fault or arc-fault protection on a circuit, the CHF alone won't satisfy it.
10) What is the clamshell pack option on Eaton CHF breakers?
Clamshell is retail blister packaging rather than bulk, offered on the 15A (CHF115CS), 20A (CHF120CS), and 50A (CHF150CS). The breaker inside is the same device as the standard catalog number. Buyers stocking a counter or a shelf want the CS; a contractor filling a panel is usually better off with the plain number.
