Eaton CSH2100N – Frequently Asked Questions

1) What is the difference between Eaton CSR and CSH circuit breakers?
The interrupting rating. The Eaton CSR two-pole breakers are rated 25 kAIC and the CSH versions are rated 35 kAIC. Everything else lines up: both are two-pole, both are rated 120/240 V, and both are offered in 100A, 125A, 150A and 200A. Pick the CSH when the available fault current at the service exceeds 25 kA or the drawing calls for a 35 kAIC main.
2) Will an Eaton CSH2200N breaker fit in my Eaton CH load center?
These CSR/CSH main breakers are specified for use in Eaton Type ECB unit enclosures, and they are the CH main circuit breaker design. They are not plug-on branch breakers for a standard CH panel interior. If you are replacing a main in a Type ECB unit enclosure, this is the right family; for a branch space in a CH load center you need a plug-on CH branch breaker instead.
3) I manage apartment buildings with Eaton meter stacks. Is this the breaker for the tenant disconnects?
Yes, if the disconnects are Eaton Type ECB unit enclosures. That is the exact application these CSR and CSH mains are called out for, at 120/240 V single-phase, two-pole. For standardizing a building, pick one amperage (100A and 125A are the common tenant sizes here) and one interrupting rating, 25 kAIC for the CSR or 35 kAIC for the CSH, so replacements stay interchangeable across the stacks.
4) What amperage ratings does the Eaton Type CSR/CSH two-pole breaker come in?
Four sizes: 100A, 125A, 150A and 200A. Each size is built in both interrupting ratings, so a 150A service can take either the CSR2150N at 25 kAIC or the CSH2150N at 35 kAIC. A 200A residential or small commercial main would use the CSR2200N or CSH2200N.
5) Can I use this Eaton two-pole breaker on a 208Y/120 three-phase system?
It is rated 120/240 V and is a two-pole device, so it is intended for single-phase 120/240 V service. Feeding two poles from a 208Y/120 three-phase panel is a different application and is not what this voltage rating covers. For 208Y/120 distribution, specify a breaker carrying that voltage rating.
6) Does a two-pole main breaker disconnect both hot legs at once?
It does. Both poles are tied so a trip or a manual throw opens both ungrounded conductors of the 120/240 V service together, which is what you need for a service disconnect rather than a pair of single-pole breakers handled separately.
