Selection Notes

The L-S-I MicroLogic 5.3 E adds an adjustable short-time delay and an adjustable instantaneous stage to the long-time overload function, plus an LCD display with an integrated energy meter. Choose it over the 2.3 variant when the switchboard needs metering data or zone-selective interlocking (ZSI) for coordinated tripping with downstream devices. At 75 kA Icu at 660/690 V AC, the HB1 frame targets 690 V applications needing 75 kA at 660/690 V.
