FAQs
Install the JKS-1 using ferrule-end contacts into standard Bussmann series holders. Ensure the panel rating matches 600 V and the circuit load is within the 1 A rating. Verify correct alignment and seating to maintain the 200 kAIC interrupt capability, then re-energize and test with appropriate protective devices in place.
The JKS-1 is a 1 A, 600 V Class J fuse with a 200 kAIC interrupt rating. These specifications enable fast protection of low-current control circuits while tolerating high fault currents up to 200 kiloamperes on 600-volt systems.
Yes. The fuse has ferrule end x ferrule end connections and a single element design, making it compatible with common Bussmann series holders used in control panels and power distribution blocks, facilitating straightforward replacement without adapters.
Yes. The JKS-1 is CE marked and RoHS compliant, signaling conformity with European safety directives and environmental standards, which supports compliance reporting and regulatory acceptance in EU projects.
Using the JKS-1 improves uptime by reducing nuisance trips due to precise 1 A protection, minimizes equipment damage from short circuits thanks to 200 kAIC interruption, and simplifies logistics with standard packaging (10 per pack) for easy stocking and quick field replacements.
