FAQs
KAB-17-1/2 is designed for Tron rectifier fuse holders and standard Bussmann clip styles. It features the compact 0.5 in by 0.5 in cross-section and a 1.98 in height, which fits many standard panel assemblies. When replacing older fuses, verify clip type, mounting pitch, and isolation clearances to ensure a safe and reliable fit.
The fuse is rated at 17.50 A and designed as a high-speed device for fast fault clearing. Response time varies with fault current and circuit conditions, but the Tron family is engineered for rapid interruption to protect rectifier circuits and downstream components, helping minimize downtime and damage during faults.
Yes. The KAB-17-1/2 belongs to Eaton's Tron TRON Rectifier fuse family, specifically engineered for fast protection of rectifier modules and DC power paths. Its compact footprint is ideal for crowded control panels, and its fast clearing reduces stress on diodes, transformers, and switching devices while maintaining serviceability.
Certification details are region-specific; refer to the datasheet for exact approvals. Generally, Tron fuses align with common standards such as UL recognition in North America and CE marking for Europe, with RoHS compliance. Always verify current certifications with Eaton or the official datasheet to ensure regulatory compatibility for your installation.
A properly rated high-speed fuse reduces unplanned downtime by preventing damage from faults. The compact size simplifies stocking and replacement, lowering spare parts costs. For best ROI, maintain a small, matched set of spares for critical rectifier assemblies and schedule regular inspections to ensure fuse status and panel integrity remain optimal.
