The Eaton Industries NZMB M power circuit-breaker, with a nominal continuous current Iu of 125A and a nominal switch-off capacity Icu at 400 53kA, covers all applications with only four compact sizes, suitable for the IEC market. It includes an adjustable range for overload protection from 960 – 1600A and adjustable range for instantaneous short circuit from 960 – 1600A. Its main circuit connection method is screw connection, with three poles. It is adaptable due to the modular function groups and features thermomagnetic release for motor protection. This complies with tripping class 10A, IEC/EN 60947-4-1, and IEC/EN 60947-2 circuit-breakers meet all requirements of the switching category AC-3.
