Bussmann FNQ-R-8 8A 600V AC Class CC Time-Delay Fuse

Description

Bussmann FNQ-R-8 8A 600V AC Time-Delay Fuse

The Bussmann FNQ-R-8 is a Limitron Class CC time-delay fuse manufactured by Eaton. Designed for electrical circuit protection, it combines a dual-element, current-limiting design with time-delay characteristics that accommodate suitable inrush currents while providing protection against specified overcurrent conditions.

This fuse is intended for compatible electrical installations that require a Class CC, rejection-type fuse.

– Small control transformer protection
– Industrial control panels
– Electrical branch circuits
– Line protection in suitable equipment
– Control circuits with appropriate inrush-current requirements

Compatibility and Selection Guidance

Before installation or replacement, verify the fuse’s current rating, operating voltage, Class CC designation, dimensions, interrupting rating, and holder compatibility. Use a compatible fuse block designed for the required fuse class.

Although this is a time-delay fuse, it must not be substituted for another fuse type solely because the amperage matches. Confirm the equipment manufacturer’s requirements and the circuit’s fault-current rating. The specified voltage rating is 600V AC; do not assume the same rating applies to DC circuits.
