Eaton FWH-500A High Speed Fuse - UL Recognized

High-speed interruption minimizes damage and downtime by rapidly isolating faults, protecting expensive drives and downstream electronics. Business impact: reduced repair costs, less production disruption, and improved equipment reliability in automation lines. Application: ideal for motor drives and power-distribution panels where fast fault clearance is essential. The 750 Vac and 750 Vdc ratings support both AC and DC fault conditions, enabling a single protective device to cover diverse loads and simplifying BOMs and maintenance planning. With 500 A RMS capacity and a 200 kAIC at 1000 Vac (and 50 kAIC at 500 Vdc), the fuse delivers robust protection for high-energy systems, minimizing arc energy and extending equipment life. This translates into measurable uptime gains for manufacturing lines and distribution frames. Installation compatibility includes blade end x blade end connections with stud mounting, offering flexible integration into standard Eaton Bussmann series enclosures and reducing installation time. The watt losses are documented at 84 W, providing predictable energy performance during continuous operation. Compliance with CE, RoHS, CSA, and UL recognizes safety and regulatory readiness, supporting audits and supplier qualification programs. These attributes together enable safer panels, easier retrofits, and lower total cost of ownership across industrial facilities.
