The Eaton Industries NZM M motor protection switch, with dimensions of 105x149x184mm, has an overload setting range of 110-220A and a nominal continuous current (Iu) of 220A. The device is designed for fixed installation, with a screw-based connection method for the main current circuit, and includes an electronic shutdown technology. The NZM..-ME series circuit-breakers are adaptable due to modular function groups, suitable for the IEC market and have an electronic release for motor protection with phase failure sensitivity. This includes IEC/EN 60947-4-1, IEC/EN 60947-2, r.m.s. value measurement, thermal memory, and an adjustable time delay setting to counter current peaks tr:2-20 at 6xIr and infinity, without overload release.
