Time-Delay Performance for High-Inrush Circuits

Control transformers and other inductive electrical loads can draw temporary inrush current when energized. The time-delay characteristic of the FNQ-R-2 allows the fuse to tolerate normal short-duration inrush conditions while maintaining overcurrent protection for the circuit.

This operating characteristic helps reduce unnecessary fuse openings during normal equipment startup. The correct fuse rating must still be selected according to the equipment manufacturer's instructions and applicable electrical requirements.

Class CC Current-Limiting Protection

The Bussmann FNQ-R-2 provides current-limiting protection during high-level short-circuit conditions. By limiting the amount of fault current that passes through the circuit, the fuse helps reduce the potential for damage to downstream electrical equipment.

Its 200 kA interrupting rating makes it suitable for properly designed industrial and commercial systems where high available fault current may be present.

Rejection-Style Design

The rejection-style construction is intended for use with compatible Class CC fuse blocks and holders. When installed in an appropriate rejection-style holder, it supports correct fuse-class selection and helps prevent the use of incompatible supplementary fuse types.

The FNQ-R-2 can also fit compatible standard Class CC fuse holders that meet the required voltage, current and interrupting ratings.

Compact Industrial Fuse Format

With nominal dimensions of 1.50 inches long and 0.41 inches in diameter, the FNQ-R-2 provides Class CC protection in a compact cylindrical package. Its ferrule end connections support installation in compatible DIN-rail, panel-mount, open-style and in-line fuse holders.

Standards and Compliance

• UL Listed to UL 248-4, Class CC
• CSA Certified, Class CC
• CE marked
• RoHS compliant

Important Selection Information

Before ordering, verify the complete manufacturer part number FNQ-R-2, the required 2 amp current rating, the 600 Vac voltage rating, the available fault current and the compatibility of the installed Class CC fuse holder.

A fuse should not be selected only by physical size. Current rating, voltage rating, operating characteristic, fuse class and interrupting rating must all meet the requirements of the equipment and electrical system.

Ordering Information

Order using the complete catalog number Eaton Bussmann FNQ-R-2. Confirm the required quantity, equipment compatibility and fuse-holder specifications before purchase.
