3.2.2 Multi-function performance of intelligent release 3.2.2.1 Ammeter function Display maximum phase current of major loop on digital pipe. Press select and display corresponding phase current of indication lamp. 3.2.2.2 Voltage function Display maximum phase voltage of major loop on digital pipe. Press select and display corresponding phase voltage of indication lamp (installation as per requirements).
3.2.2.8 Thermal Simulation Function Through overload and short-time delay after the release is tripped, it will have the memory function with the characteristics of simulation and bimetallic strip. The discharging of overload energy lasts 30 min, and the short-time delay energy 15 min. In the meantime, if there is anything wrong with the overload or short-time delay, the tripping time will be shortened;...
