Selection Notes

On the R frame, the 200 kA breaking capacity at 380/415 V AC covers standard distribution boards without needing a higher-rated frame. The MicroLogic 6.3 E trip unit adds adjustable ground-fault protection, with its own time delay, on top of the long-time, short-time and instantaneous stages, the choice when earth-fault discrimination is required upstream. The 5.3 E variant covers the same long-time, short-time and instantaneous functions without ground-fault protection, and the 2.3 unit is the fixed-settings baseline.
