Selection Notes

The HB1 frame trades breaking capacity for 690 V AC suitability, so pick it over the standard R frame when the installation runs at 690 V AC and a 75 kA breaking capacity at that voltage is sufficient. The MicroLogic 2.3 trip unit gives fixed long-time and short-time protection plus a non-adjustable instantaneous stage at 6900 A, which suits circuits where settings do not need field tuning. Choose the 5.3 E or 6.3 E variant instead when the installation needs an adjustable short-time delay, zone-selective interlocking, or an integrated energy meter.
