Equipment Type and Primary Applications
This inline fuse holder provides single-circuit overcurrent and short-circuit protection for solar power circuits. It connects directly between compatible solar panels, extension cables, and other photovoltaic wiring without cutting or splicing conductors. The sealed holder is designed for outdoor solar installations and accepts a replaceable 10A, 15A, 20A, or 30A fuse.

Safety Features and Certifications
The holder uses a sealed design, auto-locking solar connectors, and flame-rated UL94 V-0 insulation. Its replaceable fuse protects one solar circuit against overcurrent and short circuits. The product is specified with CAT III overvoltage protection and Safety Class II construction.
Installation and Maintenance Requirements
Installation uses standard MC4-compatible solar connectors for plug-and-play connection to solar panels and extension cables. No wire cutting or splicing is required. Maintenance consists of replacing the fuse with the selected 10A, 15A, 20A, or 30A rating when circuit protection operates.
Warranty and Service Information
The replaceable-fuse design supports field service by allowing the protective fuse to be changed without replacing the holder.
