Eaton FWPQ-450A High Speed Fuse - RoHS Compliant
Part Number: FWPQ-450A
Quick Summary
FWPQ-450A is a high speed fuse designed for fast protection in electrical distribution and motor drive circuits. Engineers frequently contend with nuisance outages and costly downtime caused by slower, non-selective fuses. RoHS compliance ensures regulatory alignment for electronics manufacturing, with factory-ready documentation available for audit trails and compliance records. The FWPQ-450A delivers reliable interruption at 450 A, helping maintain uptime while enabling tighter protection coordination. For procurement teams, this fuse offers predictable performance, easy stocking, and compatibility with common Eaton Bussmann protection architectures, supporting streamlined maintenance and reduced total cost of ownership in automation and process industries. Additional certifications such as CE or UL can be discussed with the factory to meet broader compliance needs.

FAQs
Ensure panel mounting compatibility with standard Bussmann series fuses, using compatible holders and clearances for heat dissipation. Verify circuit wiring follows the fuse's amperage rating and fuse-holder specifications, and plan for routine inspection during scheduled maintenance to prevent thermal buildup in crowded enclosures.
Its 450 A high-speed response interrupts fault currents rapidly, reducing damage to drive electronics and wiring. This supports selective coordination with downstream protection and minimizes downtime during motor starts, ramps, and transient faults common in conveyors and automated lines.
The device is RoHS compliant, aligning with European and global electronics waste restrictions. For broader compliance needs, CE or UL verifications can be explored with Eaton upon project or customer requirements.
The fuse measures 2.7 inches in length, 5.29 inches in height, and 2.1 inches in width, with a weight of approximately 1.6 pounds. These dimensions support straightforward panel integration and compatibility with standard fuse blocks.
