Technical data All technical specifications apply to "3-phase 4-wire system with earthed neutral conductor", unless explicitly stated otherwise. |
Full scale value of the measuring range of the neutral conductor current The full scale value of the measuring range of the neutral conductor current always corresponds to the maximum current of the terminal (EL3413 = 5 A and EL3433 = 10 A) and cannot be switched. |
