The LV432074 is a Schneider MicroLogic 6.3 E-M electronic trip unit for the ComPact NSX630 frame, rated 500 A across 3 poles and built for motor protection duty. It carries LSIG protection functions — long-time, short-time, instantaneous, and ground-fault — with zone selective interlocking (ZSI) for coordinated tripping in a motor branch. Long-time pickup (Ir) adjusts from 250 to 500 A, with selectable trip classes 5, 10, 20, or 30 to match motor starting profiles.
