Key Features and Benefits
Fast-Acting Current-Limiting Protection
The JKS-40 is designed to limit fault current under appropriate circuit conditions, helping reduce the potential effects of short-circuit faults on protected electrical equipment.
High Interrupting Rating
Its published 200kA interrupting rating at 600V AC supports use in qualifying high-fault-current circuits. The available fault current and the system’s voltage must remain within the fuse’s ratings.
Class J Design
The Class J specification helps identify the correct fuse type for compatible fuse holders and equipment. Physical fit alone does not establish electrical compatibility.
Typical Applications
Depending on the equipment manufacturer’s requirements and the installation design, the Bussmann JKS-40 may be used in:
– Electrical power panelboards
– Machinery disconnects
– Industrial electrical distribution systems
– Compatible branch-circuit protection assemblies
