FAQs
The JKS-25 is designed for industrial control panels and machine protection. Its 25 A rating at 600 V and 200 kAIC interrupt capacity make it suitable for protecting power supplies, relays, and motor control circuits in manufacturing environments. The ferrule-end design supports quick, robust field installation, while its current-limiting action helps minimize arc energy during faults.
As a fast-acting, current-limiting Class J fuse, the JKS-25 detects overcurrent conditions quickly and interrupts the circuit to prevent damage to downstream components. The 200 kAIC interrupt rating at 600 V ensures it can safely withstand high fault currents, while maintaining selectivity with upstream protection for improved system reliability and reduced downtime.
Yes. The JKS-25 features ferrule-end x ferrule-end connections and is designed to fit standard Bussmann-series fuse holders and panels. This compatibility reduces installation time, minimizes wiring errors, and supports consistent electrical cabinet practices across equipment lines.
The JKS-25 is CE Marked and RoHS Compliant, indicating conformance with essential safety, environmental, and regulatory requirements. For manufacturers, this simplifies compliance reporting, enhances supplier qualification, and supports regulatory audits in regulated industries such as food, pharma, and general manufacturing.
Using the JKS-25 can reduce maintenance overhead by limiting nuisance trips and enabling quicker fault isolation. Its robust interrupt rating and durable ferrule-end design translate to longer service intervals, fewer panel outages, and lower total cost of ownership in automated lines, especially where high fault currents or frequent startup transients occur.
