FAQs
To install BK/FWH5-020A6F, power down the equipment, open the panel, and locate a compatible Bussmann series fuse holder. Insert the fuse fully into the holder until it seats firmly, ensuring the orientation is correct for a non-indicating design. Close the panel, re-energize, and verify circuit protection with a continuity or insulation check as per your standard procedure.
The fuse is rated for 20 A, with a voltage rating of 500 V and an interrupt rating of 50 kAIC. These specs support fast fault interruption in medium-voltage control circuits and power distribution applications, helping to protect downstream components from overcurrent conditions while maintaining system reliability.
Yes, BK/FWH5-020A6F is designed for typical 50/60 Hz AC control circuits and panel boards, offering high-speed protection. For DC applications or drives, consult the datasheet to confirm suitability and any derating requirements, ensuring the fuse is used within its rated capabilities.
BK/FWH5-020A6F is CE Marked and CSA Certified, indicating compliance with European safety requirements and North American standards. These certifications support regulatory acceptance, facilitate cross-border procurement, and help ensure the fuse meets essential safety and performance criteria for industrial installations.
The high-speed interruption minimizes downtime and equipment damage from faults, lowering repair costs and unscheduled outages. Standard packaging of 100 units simplifies inventory management, reduces spares stocking costs, and accelerates replacement cycles in manufacturing lines, improving overall equipment uptime and project ROI for industrial facilities.
