Selection Notes

The HB2 frame keeps a 100 kA breaking capacity even at 690 V AC, making it the choice over the HB1 frame when the 690 V AC circuit demands a higher fault rating. The MicroLogic 5.3 E trip unit adds an adjustable short-time delay and instantaneous pickup from 1.5 to 11 x In, plus zone-selective interlocking and an LCD energy meter, so the breaker can coordinate selectively with downstream devices. Pick the 6.3 E variant instead when ground-fault protection is required, or the 2.3 unit when a simpler, non-communicating trip unit is enough.
