Eaton Bussmann Limitron JKS-500 Class J Fast-Acting Fuse 600V 500A
Available is a used Eaton Bussmann JKS-500 fast-acting fuse. This Class J fuse is engineered to provide high-level current limitation and a 200kA interrupting rating, making it an essential component for protecting sensitive semiconductor devices and general industrial circuits.
Technical Features
High-Speed Protection: Designed to open quickly under fault conditions, minimizing the total energy let-through ($I^2t$) to downstream components.
Compact Footprint: Class J fuses provide a smaller space-saving design compared to older Class H or K fuses while maintaining superior performance.
Industry Standard: Widely used in HVAC systems, motor control centers, and electrical distribution panels requiring high-interrupting capacity.
Condition Details
Functional Status: Pulled from a decommissioned panel. The fuse body remains structurally intact and the contact blades are straight.
-
Cosmetic Condition: Shows visible cosmetic wear consistent with prior installation and storage.
The label/body may show scuffs, scratches, or minor stains.
