Product FAQs
8 answersWhat load centers are compatible with the Eaton CSR2100 main breaker?
This breaker is designed for use as a main breaker in Eaton Type CH load centers. It is also compatible with Type ECC and ECB unit enclosures.
Can the CSR2100 replace an older BWH2100 main breaker?
Yes. The CSR2100 and BWH2100 share the same physical footprint and 25kAIC rating. They can be interchanged as long as your load center publication lists both types.
What is the difference between the CSR2100 and the CSR2100N?
The CSR2100N is the newer catalog kit number for the same breaker. Both share the exact same physical dimensions, 100-amp rating, and 25kAIC interrupting capacity.
Is the CSR2100 interchangeable with a BW2100 breaker?
While they share the same physical footprint, the BW2100 has a lower 10kAIC interrupting rating. The CSR2100 provides a higher 25kAIC rating and can replace the BW2100 if the panel labeling permits it.
What wire sizes are accepted by the lugs on the CSR2100?
The oversized load-side lugs on this breaker accept copper or aluminum wire ranging from 2 AWG up to 300 kcmil.
How does this main breaker mount inside the panel?
The CSR2100 features a base mount, bolt-on design that secures directly to the bus in compatible Type CH load centers and enclosures.
What type of trip mechanism does the CSR2100 use?
It utilizes a fixed thermal-magnetic trip unit, providing both long-time overload protection and instantaneous short-circuit protection.
Can this breaker be used as a service disconnect?
Yes, when properly installed in an approved main breaker enclosure or load center, it serves as the primary service disconnect for the electrical system.
