Descriere
Circuit-breakers of the NZM..-ME..NA series cover all applications with only four compact sizes and are suitable for the IEC market. The mounting is always flexible due to the modular function groups. With electronic release for the motor protection with phase failure sensitivity. Notes: switches conform to UL/CSA as well as the IEC regulations. IEC switching performance values are contained on the rating plate. 100% rated. For use in motor circuits with contactor. additional motor protective characteristics (calibration) to UL508, CSA-C22.2 No. 14-05 . Adjustable overload releases Ir, adjustable time delay setting to overcome current peaks tr:2-20s at 6xIr
