FNQ-1-1/2~FNQ-1-1-2~BUSS MIDGET FUSE
Time-delay operation is a core FNQ feature that accommodates motor inrush currents without immediate interruption. The business impact is clearer uptime and reduced warranty calls, especially on equipment with frequent starts. In practice, use this fuse in motor starters or drive circuits where brief surges are expected, such as conveyors, pumps, and fans. This reduces downtime and improves productivity in critical lines. The high interrupt rating of 10 kAIC at 500 V ensures short-circuit events are contained within the panel, protecting feeders and downstream devices. The business impact is minimized arc energy and safer shutdowns, lowering repair costs. Applications include feeder protection in switchboards and motor control centers in industrial facilities. Nickel-plated bronze endcaps and ferrule-end connections provide rugged durability and easy field installation. The business impact is fast, reliable assembly and fewer damaged connections during maintenance. It is compatible with standard ferrule-ended leads and Bussmann-series components, simplifying stocking and replacement. CE and RoHS compliance offer regulatory assurance for global projects and multinational facilities. The business impact is easier project approvals and reduced compliance risk. Use this fuse where global sourcing and product traceability are important for projects in manufacturing, energy, and process industries. Standard packaging and compact form factor enable efficient inventory management and quick replacement in tight spaces. The business impact is lower warehousing costs and faster MTTR. In practice, installers benefit from a single, standard SKU that fits common fuse holders and panelboards.

FAQs
The FNQ-1-1/2 fuse is intended for motor control circuits and panels that use ferrule-end terminations. Rated at 1.5 A and 500 V with a 10 kAIC interrupt rating, it protects starters, drives, and transformers while tolerating inrush without nuisance trips. It couples with standard Bussmann series components for easy replacement and minimal downtime.
It uses a time-delay characteristic that tolerates brief surges during motor start-up rather than tripping immediately. This reduces nuisance trips and maintains line continuity during frequent starts. The 1.5 A rating and 500 V capability make it suitable for typical starter motors, pumps, and conveyors in industrial environments. This approach helps maintain equipment uptime and reduces maintenance overhead.
Yes. The FNQ-1-1/2 fuse is CE marked and RoHS compliant, aligning with global environmental and safety standards. Its non-indicating design and nickel-plated bronze endcaps support durable operation in diverse industrial facilities. Using this fuse helps satisfy regulatory requirements while simplifying supplier qualification and traceability across multinational projects. It also ensures compatibility with common control panels and eliminates sourcing ambiguity in global deployments.
The FNQ-1-1/2 carries CE marking and RoHS compliance, reflecting European and global regulatory adherence. It features a 1.5 A current rating, 500 V voltage rating, and a 10 kAIC interrupt rating, enabling safe installation in standards-compliant equipment. Nickel-plated bronze endcaps and ferrule-to-ferrule connections further support reliable assembly. These features simplify compliance documentation and field service.
Choosing the FNQ-1-1/2 supports higher uptime and lower maintenance costs by reducing nuisance trips and unplanned downtime in high-inrush environments. Its standard ferrule-end design speeds installation, while the standard packaging minimizes inventory complexity and simplifies stocking. Long-term, this translates to faster MTTR and predictable service levels across automation systems.
