The Eaton Industries MCCB circuit-breaker is designed for a nominal continuous current of 63A and a nominal voltage of 440V, with a nominal breaking capacity of 25kA at 400. The overload protection adjustment range is between 63 – 80A and the un-delayed short circuit adjustment range is between 50 – 63A. This built-in unit is characterized by fixed installation, providing flexibility in application. The Series NZM covers all use cases with just four compact sizes and is suitable for use in both the IEC and UL market.
