The Eaton Industries NZMN M power circuit-breaker has a nominal continuous current Iu of 200A, with a nominal cut-off capacity Icu at 400 105kA. It features adjustment ranges for overload protection and non-delayed short circuit of 1500 – 2500A. The main power circuit connection method is screw connection in a 3-pole configuration. This breaker belongs to the NZM..-M series which is designed for IEC markets and allows flexible mounting due to its modular function groups. It comes with a thermomagnetic release for motor protection and fulfills all requirements of the switching category AC-3 as per IEC/EN 60947-4-1 and IEC/EN 60947-2 circuit-breaker standards. Note that it has a tripping class of 10A.
