Eaton FWP-45 High Speed Fuse - 250 Vac/dc, Non Indicating
Part Number: FWP-45
Quick Summary
Eaton FWP-45 high speed fuse provides fast interruption for industrial control circuits in drives, panels, and machines. Engineers often face nuisance trips and tight maintenance windows that disrupt production; this fuse helps minimize those interruptions while delivering reliable protection. While the product page lists a 250 Vac/dc rating and standard packaging, exact certification details require factory confirmation. In practice, Bussmann series fuses are aligned with common industry standards and tested for robust performance in electrical protection and circuit protection applications. For automation projects, the combination of a compact form factor, a standard catalog footprint, and a non-indicating option supports streamlined procurement and faster field replacements, reducing downtime and inventory complexity.

FAQs
The FWP-45 is designed for 250 Vac/dc circuits and fits standard Bussmann-series protection schemes. It uses a compact 0.75 in length by 0.75 in width form factor with a 4.35 in height, making it suitable for control panels, drives, and automation racks. For installation, verify panel space, torque requirements on terminations, and ensure the catalog references match FWP-45 before sourcing spares.
The FWP-45 is a high speed fuse intended to rapidly interrupt in fault conditions, protecting sensitive electronics and control circuitry. This results in faster fault isolation and reduced damage to downstream components. It is offered in standard packaging and a non-indicating variant, which simplifies panel wiring. Use this fuse where rapid clearance of short-circuit faults is critical to uptime.
Yes, with a 250 Vac/dc rating and a compact form factor, the FWP-45 is well-suited for industrial automation applications, including drives, PLC panels, and machine control interfaces. Its high-speed interruption helps prevent cascading faults, while standard packaging supports efficient stocking. Confirm the exact load currents and replacement intervals in your system design datasheets.
The product page lists compliance as ‘Contact factory / Contact Manufacturer,’ so explicit certifications are not published here. For regulatory alignment, request current certification documentation from Eaton, and consult the accompanying datasheets or catalogs for UL/IEC/CE references typically associated with Bussmann-series fuses. Always verify the latest certified status before mission-critical deployments.
Adopt a maintenance strategy that keeps a quantity of readily available spares based on historical fault rates in your lines. The FWP-45’s standard packaging and non-indicating design simplify stocking and replacement. By coordinating with your preventive maintenance plan and ensuring quick field swaps, you reduce downtime costs and improve line throughput while maintaining consistent protection across control circuits.
