Product overview A 100A photovoltaic fuse with color code 4 for quick visual identification. Designed for use in solar PV circuits that require a 100 ampere PVrated fuse. Key benefits Clear identification: Color 4 marking makes it fast to locate and verify the correct fuse during inspection and maintenance. Protects PV circuits: Sized for 100A PV applications to isolate faults and prevent damage to downstream components. Easy replacement: Standard 100A PV form factor fits common PV fuse holders and combiner boxes for straightforward service. Minimizes downtime: Quick visual sorting and direct replacement reduce maintenance time onsite. Important attributes Size and rating: 100A(PV) rating suitable for photovoltaic string and array circuits specified for 100 ampere fuses. Color code: Color 4 for simple and consistent identification among multiple fuses. Function: Overcurrent protective device intended to interrupt fault currents in PV circuits when installed in the appropriate fuse holder. Compatibility: Intended for use with PV fuse holders, combiner boxes, and equipment that accept 100A PV fuses. Confirm compatibility with the fuse holder and system specifications prior to installation. Practical applications Residential solar array: Protect individual PV strings inside a rooftop combiner box where a 100A PV fuse is required. Commercial or utility scale installations: Use in combiner boxes or array protection points for sections rated at 100A. System service and maintenance: worn or blown 100A PV fuses during routine servicing to restore circuit protection. Installation notes Verify system is deenergized before replacing the fuse. Confirm fuse holder and surrounding equipment are rated for 100A PV fuses. Match the color code and rating to the original part to maintain correct circuit identification. This product is supplied as a 100A PV fuse with Color 4 identification for use in photovoltaic systems requiring that specific rating and visual code.
