FAQs
The FWP-90A uses a stud mounting method, requiring a compatible fuse holder or panel bus with a suitable stud terminal. Plan for secure torque during installation to avoid loose connections in vibration-heavy environments. Its 4.59 in length and 1.32 in width fit standard spaces in Bussmann series baseloads, facilitating straightforward retrofits.
Rated at 90 A with a voltage rating of 250 Vac/dc, the FWP-90A is suited for high-current feeders, motor drives, and power distribution in industrial control panels. It provides fast overcurrent protection for both AC and DC circuits, helping prevent equipment damage and reducing downtime in automation and manufacturing environments.
Yes, the FWP-90A is RoHS compliant, addressing environmental and regulatory concerns. Eaton notes that additional certifications can be provided upon request, so consult the factory for CE, UL, or other regulatory documentation as needed for your specific application and region.
Non-indicating fuses do not provide a visual blown-status indicator, which can simplify component sourcing and reduce costs in dense assemblies. For fault diagnosis, plan for circuit testing or add an external indication scheme in critical lines. This keeps the fuse selection cost-effective without compromising protection reliability.
By providing precise, fast clearing at 90 A and 250 Vac/dc, the FWP-90A minimizes fault energy, reduces unplanned downtime, and protects expensive drive and control hardware. The robust stud mount and standard packaging support faster installation and lower maintenance costs, yielding faster payback in production lines and critical automation loops.
