Product FAQs

8 answers
Which load centers are compatible with the CH2100 circuit breaker?

This breaker is designed exclusively for Eaton and Cutler-Hammer Type CH load centers. It will not fit in Type BR load centers, as CH series breakers feature a 3/4-inch per pole footprint and a different busbar clip design.

Can I substitute an Eaton BR2100 for the CH2100?

No. While both are Eaton 100A, 2-pole breakers, they belong to completely different product lines. The CH2100 has a tan handle, requires 3/4-inch per pole spacing, and fits Type CH load centers. The BR2100 has a black handle, requires 1-inch per pole spacing, and fits Type BR load centers. They are not physically interchangeable.

How much panel space does the CH2100 require?

As a 2-pole breaker in the CH series, it requires two 3/4-inch spaces, occupying a total of 1.5 inches on the panel bus.

Can the CH2100 be used as a backfed main breaker?

Yes. When installed as a backfed main in a compatible Type CH load center, the National Electrical Code requires the breaker to be mechanically secured to the busbar. You must use an approved Eaton hold-down kit, such as the CH125RB or CHPHD, depending on your specific panel model.

What are the wire and temperature requirements for the CH2100 terminals?

The box lugs accept 10 AWG to 1/0 AWG copper or aluminum conductors. Per Eaton specifications, you should use wire rated for 60 or 75 degrees Celsius.

Is the CH2100 suitable for HVAC equipment?

Yes, this breaker is HACR rated. It is approved for use with heating, air conditioning, and refrigeration equipment that requires a 100A, 2-pole overcurrent protective device.

How does the CH2100 indicate a tripped condition?

Unlike some breakers that trip to a center position, the standard Type CH mechanism is designed to trip fully to the OFF position. This provides a clear visual indication and eliminates nuisance callbacks from partial trips.

Does the CH2100 have a common trip mechanism?

Yes, it features an internal common trip connection. If an overcurrent or short-circuit fault occurs on one leg of the 120/240V circuit, the mechanism will open both poles simultaneously to ensure the entire circuit is safely de-energized.

    Got 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!
