Feature → Business Impact → Application: The FWP-350A delivers 350A RMS protection, enabling precise fault interruption without unnecessary activations in high-current applications. This reduces conductor wear and minimizes downtime during faults, translating to lower maintenance costs in motor drives and power distribution panels. Application: protection of large industrial drives and automated lines where rapid disconnection improves equipment longevity. Feature → Business Impact → Application: Ultra-wide voltage capability (1400 Vac, 2100 Vac, and 1000 Vdc depending on version) supports mixed panel designs, lowering spare inventory and simplifying procurement. Application: data centers, process plants, and packaging lines needing versatile protection in mixed-voltage environments. Feature → Business Impact → Application: 50 kAIC at 700 Vdc and 200 kAIC Vac interrupt ratings provide high fault current handling, increasing system safety and reducing arc exposure risks. Application: high-energy circuits and switchgear assemblies where fault current levels are uncertain. Feature → Business Impact → Application: Non Indicating status with blade end x blade end and stud mounting options enables flexible integration in compact enclosures and retrofit projects. Application: control cabinets and machine local disconnects where space is tight. Feature → Business Impact → Application: 65 W watt losses balance reliability with energy efficiency, supporting cooling and operational costs in continuous-run environments. Application: continuous production lines where heat management and efficiency matter for OEE. Feature → Business Impact → Application: CSA Certified, UL Recognized, CE Marked, and RoHS Compliant streamline regulatory approvals across regions, reducing time-to-operational readiness. Application: global deployments in North America and Europe with standardized compliance requirements.

FAQs
The FWP-350A supports blade end x blade end connections and stud mounting, offering flexible installation in control panels and power distribution assemblies. Use proper torque on stud terminals, observe clearance for 2.4 in length, 5.4 in height, and 2.9 in width, and note it is non-indicating, so external status monitoring is recommended for fault visibility.
Key specs include 350A RMS amperage, 50 kAIC at 700 Vdc, 200 kAIC Vac interrupt ratings, and voltage ratings of 1400 Vac (FWS 8-15 A), 2100 Vac (FWS 2-6 A), or 1000 Vdc (FWL/FWS 2-30 A). Watt losses are 65 W, with standard packaging and a weight of 1.7 lb.
Yes. Its high-speed interruption, high interrupt ratings, and voltage flexibility make it ideal for motor drives, power distribution panels, and machine control circuits. The non-indicating design may require external trip indication, but its mounting options and rating versatility support reliable protection in dense control gear.
The FWP-350A is CE Marked, RoHS compliant, CSA Certified, and UL Recognized. These certifications align with European and North American safety standards, support regulatory approvals, and facilitate widespread deployment in regulated industries with documented compliance.
The fuse offers robust protection that reduces fault-related damage and downtime, improving OEE in production lines. While it is non-indicating, reliable protection lowers spare part consumption and maintenance interventions, and the familiar Bussmann series compatibility simplifies stocking and procurement across multi-site facilities.
