Selection Notes

The MicroLogic 6.0 trip unit adds ground-fault protection (G) on top of long-time, short-time and instantaneous (LSI) functions, so the C160N460FM can detect low-level earth faults that the 4-pole, 1600 A NS1600N frame's phase protection alone would miss. Ground-fault pick-up is adjustable per the [Ig] range in the table above. Choose this 6.0 (LSIG) trip unit over the 5.0 (LSI) sibling when the switchboard needs integrated ground-fault tripping rather than a separate earth-leakage relay.
