Eaton's CSR breakers can operate as main breakers. The 2-pole CSR breakers can support maximum current ratings of 200 Amps and interrupt ratings of 10 or 25 kAIC. Many CSR main breakers do not operate with branch breakers. Some CSR main breakers operate in ring-type meter mains, while others operate in ringless meter mains. Some CSR main breakers can also be used in ring-type all-in-one meter devices, and these main breakers can support branch breakers. Several CSR main breakers can be installed in electrical systems in residential buildings. Many of these breakers support aluminum or copper wires with a size range of #2-300 kcmil.
