FAQs
Yes. CF363FWKW is a three-pole, fusible safety switch rated at 600 Vac and 100 A, designed for straightforward integration into common 3-phase panels. With fusible without neutral configuration, it simplifies wiring and reduces panel complexity while delivering reliable isolation for motor circuits.
CF363FWKW is CSA Certified and UL Listed, assuring compliance with recognized safety standards and regulatory requirements. These certifications support safer procurement, faster approvals in regulated environments, and mitigate risk during audits and inspections.
Ensure proper mounting clearance, weather and washdown exposure, and compliance with lockout/tagout practices. The NEMA 4X enclosure provides corrosion and water ingress resistance, making it suitable for harsh or outdoor environments where frequent cleaning or exposure to moisture occurs.
The viewing window allows quick visual verification of fuse status without opening the enclosure, reducing maintenance time, exposure to arc flash risk, and downtime during fault checks or fuse inspections.
Maintain a small spare stock of Bussmann series fuses compatible with CF363FWKW and reference Eaton catalogs for compatible fuse types. Regularly inspect the enclosure for seals and corrosion, and plan periodic fuse status checks to prevent unexpected outages in production lines.
