Description
Built for main circuit protection, the Eaton CC3150N main breaker kit uses thermal magnetic protection. It has a rated current of 150A, 120/240VAC rated voltage and a 10kAIC interrupting rating at 240V. The 3-phase, 3-pole CC series kit uses a panel bus connection and line and load side lug terminals. It provides long-time and instantaneous trip functions, UL approval and a 4-4/0 AWG wire range.Specifications

Product FAQs
6 answersWhat voltage rating should I use when selecting the Eaton CC3150N?
The Eaton CC3150N is rated 120/240VAC. Match this AC voltage rating to the circuit voltage when selecting the breaker.
How does the interrupting rating affect breaker selection?
The interrupting rating is 10kAIC at 240V. The available fault current at the installation point must not exceed that rating for a 240V application.
How are the line and load conductors connected?
The breaker has lug connections on both the line and load sides. Plan for conductor terminations at each side, keeping the incoming line and outgoing load connections distinct.
How does the thermal-magnetic trip respond to overloads and short circuits?
The thermal-magnetic trip includes long-time and instantaneous functions. Long-time operation allows a delayed response to sustained overloads, while instantaneous operation responds rapidly to high fault current.
What dimensions should I account for when planning the installation?
The breaker kit is 5.25 in high and 5.75 in wide. Use these dimensions when planning the space occupied by the kit and access for conductor termination.
What do the phase and pole ratings mean?
The Eaton CC3150N is a 3-phase, 3-pole breaker. The pole count describes the three circuit paths controlled by the breaker, an important detail when reviewing the circuit layout.
