Product FAQs
7 answersWhat panels are compatible with the Eaton CH315 circuit breaker?
This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It requires three 3/4-inch spaces and connects to the silver-flash-plated copper bus found in CH series panels. It is not interchangeable with Eaton BR or other 1-inch breaker platforms.
What wire sizes do the box lugs on the CH315 accept?
The terminals accommodate 14 AWG to 6 AWG copper or aluminum wire. Conductors should be rated for 60 or 75 degrees Celsius depending on the specific installation requirements.
Is the CH315 suitable for HVAC equipment circuits?
Yes, this breaker is HACR rated. It can be used for heating, air conditioning, and refrigeration equipment that requires a dedicated 15-amp, three-pole circuit.
How does the CH315 indicate a tripped condition?
Eaton CH series breakers feature a trip-to-OFF mechanism. When an overload or short circuit occurs, the handle moves directly to the OFF position, allowing quick identification of the tripped circuit.
How much panel space is required to install this three-pole breaker?
The CH315 requires three adjacent 3/4-inch spaces on the load center bus. It utilizes a plug-on mounting style for quick installation.
Are Eaton CH315 and Cutler-Hammer CH315 the same breaker?
Yes. Eaton acquired Cutler-Hammer, and the CH series retains the same catalog numbers and physical dimensions. The CH315 is fully backward compatible with older Cutler-Hammer CH load centers.
Does this breaker disconnect all phases during a fault?
Yes, the CH315 features an internal common trip mechanism. If a fault is detected on any single pole, all three poles will trip simultaneously to ensure complete power disconnection across the circuit.

- CSChristine S.Verified BuyerReviewingEaton / Cutler-Hammer CH2100-LONG - 100A 2 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars5/18/26Got a great refurbished breaker - saved a $6500 Service Replacement
When our main breaker frizzed out, the option we were presented with was replacing the entire panel and service due to the type and part - no longer produced for replacement parts. It would be a $6500 replacement.
We'll likely have to do it at some point but, for now, the replacement breaker we were able to source from Superbreakers (with a $25 warranty) was $5900 less expensive. installation ran a few hundred dollars and the tech said the part looked to be in excellent condition and was prepped for install as he would have hoped.
Very thankful for SuperBreakers!
