Eaton Bussmann FNQ-R-1-1/2 1.5A 600V Class CC Time-Delay Fuse

Eaton Bussmann FNQ-R-1-1/2 Class CC Time-Delay Fuse

Buy Eaton Bussmann FNQ-R-1-1/2 online.The Eaton Bussmann FNQ-R-1-1/2 is a 1.5 amp, 600 volt Class CC time-delay fuse designed for industrial control circuits, small control transformers, branch circuits, and line protection applications.

Part of the Bussmann series LIMITRON™ FNQ-R family, this fuse combines time-delay performance with current-limiting protection. Its high-inrush design helps accommodate temporary current surges commonly associated with control transformers, relays, solenoids, and other industrial control equipment, while providing rapid current limitation during short-circuit conditions.

Class CC Current-Limiting Protection

The FNQ-R-1-1/2 provides Class CC current-limiting protection in a compact 13/32-inch by 1-1/2-inch fuse format. During a high-level short-circuit event, the fuse limits fault current to help reduce thermal and mechanical stress on downstream equipment.

Its time-delay characteristic supports closer fuse sizing in circuits that experience normal temporary inrush currents. This makes the FNQ-R series particularly suitable for control transformers and similar industrial control applications where a standard fast-acting fuse may open during normal startup.

Rejection-Style Class CC Design

The rejection-style construction is designed for compatible Class CC fuse blocks and holders. When used with the correct rejection-style holder, it helps prevent the installation of supplementary fuses that do not provide the same branch-circuit protection rating.

Compliance and Certifications

• UL Listed Class CC fuse
• CSA Certified
• CE marked
• RoHS compliant

Ordering Information

Please confirm the complete catalog number FNQ-R-1-1/2, the required 1.5 A current rating, and the compatibility of your Class CC fuse holder before placing an order. Fuse ratings and physical fit must match the requirements of the equipment manufacturer and the applicable electrical system.
