Product FAQs
6 answersWhat load centers are compatible with the CH115ST circuit breaker?
The CH115ST is designed exclusively for use in Eaton and Cutler-Hammer Type CH load centers. It features a plug-on mounting style for secure connection to the panel busbar.
What does the ST suffix mean on the CH115ST breaker?
The ST suffix indicates that this breaker is equipped with a factory-installed shunt trip mechanism. This allows the breaker to be tripped remotely by applying a voltage signal to the shunt trip coil, which is commonly used for emergency stop or remote shutdown applications.
What wire sizes are accepted by the terminals on the CH115ST?
The box lug terminals on this 15-amp breaker accept copper or aluminum wire ranging from 14 AWG to 8 AWG.
Can the CH115ST be used in 240V applications?
While it carries a 120/240VAC rating, as a 1-pole breaker, it provides 120V to a single circuit. The 120/240V rating indicates it is suitable for use in a standard 120/240V split-phase system.
What type of trip mechanism does the CH115ST use?
It utilizes a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits.
Is the Eaton CH115ST the same as the Cutler-Hammer CH115ST?
Yes, Eaton acquired Cutler-Hammer and continues to manufacture the CH series under the Eaton brand. The CH115ST is the exact same breaker regardless of whether it is labeled as Eaton or Cutler-Hammer.

- 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!
