Eaton FWPQ-500A High Speed Fuse - RoHS Compliant
Part Number: FWPQ-500A
Quick Summary
The Eaton FWPQ-500A high speed fuse protects electrical systems in industrial machinery by fast interrupting overcurrent events. Customers frequently wrestle with nuisance trips, downtime, and the risk of mis-protection when choosing fuses. RoHS compliance is specified; there is no published data on SIL, CE, or IP ratings, so confirm these with Eaton if your project requires them for regulated environments or equipment in harsh industrial settings. This broad protection aligns with motor-drive and power-distribution needs, delivering dependable protection while helping procurement reduce stock and downtime. As part of the Bussmann lineup, it supports scalable, RoHS-compliant electrical protection for panel builders and OEMs.

Eaton Specification Sheet - FWPQ-500A
Feature → Business Impact → Application. The 500 A rating provides a fast-acting protective element that significantly reduces damage from short circuits, limiting downtime and extending equipment life in motor-drive applications. This translates to measurable uptime improvements and lower replacement costs for critical drives and power circuits, especially in manufacturing lines and process equipment. The compact form factor with a 2.7 in length, 5.29 in height, and 2.1 in width enables easier fitment in tight control panels, reducing enclosure redesign needs and supporting faster time-to-design. RoHS compliance helps manufacturers meet environmental standards and streamline supplier qualifications for electronics and control systems. Availability of official catalogs and the specification sheet accelerates design-in, while compatibility with the Eaton Bussmann family ensures consistent protection across assemblies. These attributes address common objections about space, compliance, and integration complexity in industrial cabinets.

FAQs
The FWPQ-500A is well suited for industrial power distribution, motor drives, and control panel applications where fast overcurrent interruption is needed. With a 500 A rating and a Bussmann high speed design, it protects drives and circuits in manufacturing equipment, process lines, and automated systems while helping engineers meet electrical protection requirements and maintain uptime.
A 500 A rating indicates the fuse can interrupt large fault currents quickly, limiting damage to conductors, controllers, and downstream components. This enables tighter protection coordination with circuit breakers and drives, reducing the risk of collateral damage during faults, and supports shorter reclosing times and improved overall system reliability in heavy-current applications.
RoHS compliance is noted for the FWPQ-500A. The spec does not provide SIL, CE, or IP rating data, so you should verify these certifications with Eaton if your installation requires them. For design validation, consult the Eaton specification sheet and the full catalog to confirm regulatory alignment with your project and regional requirements.
Plan for a compact fuse footprint in the control panel; the FWPQ-500A measures 2.7 in (L) x 5.29 in (H) x 2.1 in (W) and weighs 1.6 lb, which informs enclosure space and mounting clearance. Ensure compatibility with the Bussmann series family, check the catalog number FWPQ-500A, and reference the official datasheet during BOM creation and panel wiring to simplify installation and maintenance.
Using the FWPQ-500A can lower total cost of ownership by reducing nuisance trips and downtime, minimizing equipment damage, and extending drive life through precise, fast fault interruption. The availability of catalogs and datasheets supports faster design-in, reducing engineering hours for validation and enabling more predictable maintenance planning and spare parts budgeting.
