Fast-acting, current-limiting Class J fuse with a 20 A rating and a 200 kAIC interrupt rating at 600 Vac provides selective protection for control circuits. This reduces arc energy and limits fault severity, helping protect motors, drives, and PLC I/O from catastrophic faults in industrial equipment and panelboards. The rejection style ferrule-end design prevents improper insertion, simplifying installation and improving field reliability in high-mix panel environments. RoHS compliance ensures regulatory readiness for global deployments, supporting compliant manufacturing and easier cross-border distribution. The compact 2.25 inch length and 0.81 inch width/height enable higher panel density and easier stocking, with packaging of 10 per pack streamlining procurement. Non-indicating status requires external monitoring, which aligns with centralized diagnostics in modern automation systems, reducing field service visits and improving uptime.

FAQs
JKS-20 uses ferrule-end connections compatible with standard Class J fuse holders. Install by inserting the fuse into the holder until seated; ensure ferrule sizes match the holder specification to maintain secure, reliable connections.
JKS-20 has a 20 A amperage rating, a 600 V voltage rating, and a 200 kAIC interrupt rating at 600 Vac, providing strong fault-current protection for industrial circuits.
Yes, the JKS-20 is RoHS compliant, making it suitable for global deployment, including European applications that require regulatory conformance for electrical protection components.
JKS-20 is ideal for control panels, motor control centers, and power distribution circuits where fast-acting, current-limiting protection is required to safeguard equipment and maintain uptime.
The high 200 kAIC interrupt rating reduces fault energy, while current-limiting minimizes arc exposure. Packaging in 10-per-pack simplifies stocking, and the non-indicating design aligns with remote monitoring schemes, collectively lowering service calls and improving overall system availability.
