Product FAQs
6 answersCan I install the CH330 breaker in an Eaton BR load center?
No. The CH330 is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It utilizes a 3/4-inch per pole footprint, whereas BR panels require breakers with a 1-inch per pole footprint.
How much panel space does the Eaton CH330 require?
As a three-pole breaker, it requires three standard 3/4-inch spaces, taking up a total width of 2.25 inches on the panel bus.
Is the Eaton CH330 HACR rated?
Yes, this circuit breaker is HACR rated, making it suitable for use with compatible heating, air conditioning, and refrigeration equipment.
Does the CH330 feature an internal common trip mechanism?
Yes. The CH330 is a common trip breaker. If an overload or short circuit occurs on any single pole, the internal mechanism will disconnect all three poles simultaneously to safely interrupt power to the load.
Are Eaton and Cutler-Hammer CH330 breakers interchangeable?
Yes. Eaton acquired Cutler-Hammer and continues to manufacture the CH line. A CH330 labeled under the Eaton brand is the exact same component and a direct replacement for older Cutler-Hammer CH330 breakers.
What types of three-phase voltage systems can the CH330 protect?
With its 240VAC maximum rating, this three-pole breaker is typically applied in 208Y/120V Wye or standard 240V Delta three-phase networks for branch circuit protection.

- 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!
