Eaton FWP-50A High Speed Fuse - RoHS Compliant
Part Number: FWP-50A
Quick Summary
FWP-50A high speed fuse provides fast interruption to protect electrical circuits in industrial control panels. Engineers frequently battle nuisance trips and downtime when protection is too slow or misapplied to the circuit load. RoHS compliant construction helps streamline regulatory compliance, while the 50 A at 250 Vac/dc rating covers a broad range of loads. For panel builders and OEMs, this fuse delivers reliable, readily sourced protection with straightforward installation, reducing maintenance and spare parts requirements. That also translates to greater uptime in demanding automation environments.

FAQs
Installation uses the stud terminals provided on the fuse body. Align the fuse with the panel opening, connect the stud to the appropriate bus bar or terminal lug, and tighten to the manufacturer’s recommended torque. Ensure proper clearances around the fuse body to accommodate heat dissipation and vibration resistance in industrial environments.
The 50 A amperage rating specifies the maximum continuous current the fuse can protect. The 250 Vac/dc rating indicates suitability for both AC and DC circuits up to 250 volts. In practice, this supports protection for typical industrial loads such as motors, drives, and control circuits while maintaining fast interruption behavior.
Yes, the FWP-50A is RoHS compliant, meaning it adheres to restrictions on hazardous substances for electronics assemblies. This simplifies regulatory compliance across many regions and supports safer, easier integration into modern machinery and panel builds.
Best suited for industrial control panels, motor drives, and power distribution nodes where fast fault clearance is critical. The non-indicating, stud-mounted design plus compact footprint supports retrofit projects and space-constrained enclosures, enabling reliable protection with straightforward sourcing for OEMs and maintenance teams.
Key dimensions are 4.6 inches in length, 1.8 inches in width, and 1.12 inches in height, with an approximate weight of 0.24 lb. The fuse uses a standard packaging type and stud mounting, making it compatible with common panel layouts and mounting hardware used in industrial electrical protection schemes.
