High-speed protection is the core feature of the FWP-250A, enabling rapid interruption of fault current to minimize conductor damage. The business impact is clear: reduced arc energy, lower damage to fuses and wiring, and less downtime during faults. In practical applications such as motor drives and power distribution panels, this fast response translates to smoother startups and improved equipment availability. Interrupt capacity and fault energy management: The 200 kAIC Vac interrupt rating and 50 kAIC at 700 Vdc handle high fault currents without nuisance trips. This improves process stability on demanding lines and protects downstream components like contactors, cables, and bus bars. In real-world installations, engineers rely on these ratings to meet system safety standards while maintaining production throughput. Installation versatility: Blade-end x blade-end connections with stud mounting offer flexible mounting options in compact enclosures and retrofits. This reduces wiring modifications and accelerates commissioning, especially in retrofits or upgrades to existing protection schemes. The sturdy stud mounting also improves vibration resilience in harsh industrial environments. Compliance and reliability: CE Marked and RoHS Compliant with CSA Certified and UL Recognized certifications simplify procurement and regulatory audits across regions. The non-indicating fuse indicator and standard packaging streamline replacement in routine maintenance while maintaining consistent safety documentation. These certifications support multi-site deployments in electrical protection and circuit control panels. Efficiency and thermal management: Watt losses of 48 W minimize additional heat load inside panels, contributing to cooler enclosures and longer component life. The 250 A RMS rating supports high-current protection without compromising selectivity or coordination with upstream fuses. Overall, FWP-250A delivers dependable protection with predictable lifecycle costs for industrial power systems.

FAQs
FWP-250A supports blade-end x blade-end connections with a stud mounting method, giving installation flexibility for both modern and legacy panels. When mounting, ensure the stud is torqued to the manufacturer’s specification and verify clearances around the fuse to maintain proper ventilation. Follow UL/CSA guidelines for panel integration and replace only with the same catalog number to preserve coordination and protection levels.
The FWP-250A is rated 250 A RMS with an interrupt rating of 200 kAIC at AC and 50 kAIC at 700 Vdc. It also lists watt losses at 48 W. These ratings support fast fault clearance in high-current environments like motor drives and DC links, reducing fault energy and protecting downstream components such as cables and contactors.
Yes. The FWP-250A is CE Marked and RoHS compliant, with CSA certification and UL Recognized status. This combination simplifies procurement across regions, speeds regulatory approvals, and supports compliance audits in multinational facilities while maintaining high safety and performance standards.
The fuse measures 2.4 inches in length, 5.4 inches in height, and 2.9 inches in width, with a weight of approximately 1.7 pounds. This size supports compact enclosures and retrofit projects. Blade-end connections and stud mounting further aid layout flexibility, helping engineers optimize panel space without sacrificing protection performance.
FWP-250A is ideal for motor drives, servo systems, CNC machines, and DC bus protection within electrical protection and circuit control panels.
