Description
Designed to support residential and commercial systems, this 100A three-pole breaker provides essential overcurrent protection. It features the legacy long-style body, making it suitable for older enclosures requiring this form factor. The breaker mounts into Eaton Type CH load centers via a simple plug-on connection. As the predecessor to the modern CH3100, users must confirm panel compatibility. With a 10kAIC rating at 240V, it includes a common trip function and carries an HACR rating.Specifications

Product FAQs
8 answersWhat type of panel is required for the CH3100LONG?
This breaker is designed exclusively for Eaton or Cutler-Hammer Type CH load centers. It is not compatible with BR series or other manufacturer panels.
Can I install this 3-pole breaker in a standard residential single-phase panel?
No. The CH3100LONG is a 3-pole breaker that requires a 3-phase electrical system. Standard residential single-phase panels cannot accommodate 3-pole breakers.
How much panel space does the CH3100LONG require?
This 3-pole breaker requires three standard 3/4-inch spaces in a Type CH load center, taking up a total width of 2.25 inches.
What wire sizes do the box lugs on this breaker accept?
The terminals are designed to accept 10 AWG up to 1/0 AWG copper (Cu) or aluminum (Al) wire.
What does the LI trip function indicate on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. This means the breaker uses a thermal-magnetic mechanism to protect against both gradual overloads (Long-Time) and sudden short circuits (Instantaneous).
Can the CH3100LONG be used on a 480V system?
No. This miniature circuit breaker has a maximum voltage rating of 240VAC and is not suitable for 277/480V applications.
Does this breaker include ground fault (GFCI) or arc fault (AFCI) protection?
No. The CH3100LONG is a standard thermal-magnetic circuit breaker. It does not provide GFCI or AFCI protection.
Are Eaton and Cutler-Hammer CH breakers the same?
Yes. Eaton acquired Cutler-Hammer, and the CH series breakers are the same product line. A modern Eaton CH breaker is a direct replacement for an older Cutler-Hammer CH breaker of the same specifications.

- 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!
