Eaton’s BussmannTM series NH size 800 V a.c. fuse links are specifically designed to meet the needs of branch circuit and transformer protection in photovoltaic inverter systems. These fuse links are capable of interrupting low overcurrents associated with faulted PV systems (reverse current, multi-array fault). Table 1. Technical data.

Vertical three pole fuse switches for NH00, NH1, NH2 and NH3 size fuses. Distance between busbars 185 mm or 210 mm. Rated operational current from 250 A to 1260 A. Rated operational voltage up to 690 Vac.

The fuseholder allows using simultaneously a microswitch for NH fuse links and IP20 protection accessories.
