The Eaton Industries NZM..-S circuit-breaker, with a nominal continuous current Iu of 100A and a nominal interrupting capacity Icu of 105kA at 400V, is versatile, covering all application cases in just four compact sizes, making them suitable for the IEC market. Its overload protection range is adjustable between 600 – 1000A, as is its instantaneous short-circuit range. The main circuit connection method is a screw connection. It has magnetic short-circuit release in conjunction with an overload relay, and short-circuit release without overload trip. The unit has three poles and meets all requirements of the AC-3 switching category.
