The Eaton Industries MCCB circuit breaker operates at a nominal continuous current of 125A and a nominal voltage of 440V. It features a nominal breaking capacity of 25kA at 400. Adjustable overload protection ranges from 100-125A, as does the un-delayed short circuit setting range. This built-in device is designed for fixed installation. Additionally, the Series NZM circuit-breakers, which this device forms part of, are flexible in their installation, thanks to the modular function groups. They are compact yet versatile, meeting the needs of the IEC and UL markets with only four sizes to cover all applications.
