Description
The Eaton Bussmann FNQ-R-30 is a LIMITRON series Class CC fuse designed for overcurrent protection in compatible industrial and electrical control circuits. Its dual-element, current-limiting time-delay characteristics help accommodate specified temporary inrush currents while providing protection against qualifying overcurrent and short-circuit conditions.
Rated at 30A and 600V AC, this fuse is intended for equipment designed for its specific current rating, voltage rating, fuse class and protection characteristics.
