Product FAQs
5 answersCan the CSH2100N be used as a branch breaker in standard panels?
No, the CSH2100N is specifically designed to function as a main circuit breaker. It is compatible with Eaton CH series load centers and Type ECB unit enclosures to provide primary overcurrent protection.
Can the CSH2100N be used to replace a CSR2100N main breaker?
Yes. The CSH2100N shares the same physical footprint as the CSR2100N but provides a higher interrupting rating of 35kAIC, making it a direct, upgraded replacement when higher fault current protection is required.
What type of conductors can be landed on the CSH2100N main breaker?
The factory-installed lugs accept 2 AWG to 300 kcmil copper or aluminum wire, which covers standard service entrance cable sizes for 100A residential and commercial services.
When is the 35kAIC rating of the CSH2100N required?
A 35kAIC interrupting rating is typically required in commercial applications or specific residential locations where the utility's available fault current exceeds the standard 10kAIC or 25kAIC limits of standard main breakers.
How does the thermal-magnetic trip unit in the CSH2100N operate?
The breaker utilizes a fixed thermal element for long-time protection against sustained overloads, combined with a fixed magnetic element for instantaneous tripping during severe short circuits.
