Eaton / Cutler-Hammer CC3100N Main Breaker Kit

The Eaton CC3100N is rated 120/240VAC. Use that AC voltage rating when selecting it for the circuit, and evaluate interrupting capacity separately against available fault current.

Its interrupting rating is 10kAIC at 240V. Available fault current at the installation point must not exceed that rating, so compare the circuit's available fault current with the breaker rating before selecting it.

The wire range is AWG 4 to AWG 4/0 for copper or aluminum conductors. Select conductors within that termination range, and size them for the circuit's ampacity requirements rather than terminal capacity alone.

The Eaton CC3100N has lug connections on both the line and load sides. Plan for lug terminations for both incoming and outgoing conductors, using copper or aluminum wire within the AWG 4 to AWG 4/0 range.

Its thermal-magnetic trip has long-time and instantaneous functions. The long-time function addresses sustained overloads, while the instantaneous function responds to high-current faults without an intentional delay.

The Eaton CC3100N has three poles, providing three protected current paths. Consider the pole count together with its three-phase rating when selecting circuit protection.
