Eaton’s MagnumE IEC low voltage power breaker offers a comprehensive portfolio of breaker frame sizes and ratings up to 6300A in four basic frame sizes to meet customer needs. With an on-going need to improve rating performance and product size, Eaton now offers a 4000A frame rating option in the standard Magnum frame. This allows for maximum configuration flexibility when selecting a power breaker to meet 4000A application needs. Magnum air circuit breakers meet the needs for IEC 60947-2 control and switchgear applications. The new 4000A frame rating of Magnum is available in a standard frame drawout configuration.
