Parameter Specification Manufacturer / Series Eaton, HJD Series (Current Limiting Fuse) Model Number HJD 65k Product Type Current Limiting Fuse Rated Voltage Typically 600V AC or 690V AC (Must verify from datasheet) Rated Breaking Capacity (Icn) 65 kA (65,000 Amps RMS Symmetrical) Rated Current (In) Various ratings available (e.g., 100A, 200A, 400A, etc.). The "65k" refers to the interrupting rating, not the current rating. The specific amperage rating is a separate value that must be specified (e.g., HJD 200A 65k). Standards Compliance IEC 60269-1, IEC 60269-2 (or UL/ANSI 248-1 for relevant versions) Let-through Current (Ipk) Very low compared to the prospective fault current (Specific values can be found in peak let-through current charts). Let-through Energy (I²t) Very low, providing excellent thermal protection for downstream devices. Mounting / Style Typically a bolt-on or clip-mount design for secure connection in fuse bases or holders.
