Why Choose the Mersen A1028284 HelioProtection Photovoltaic Fuse?
The Mersen A1028284, catalogue reference HP10NH1GPV63, is a high-performance photovoltaic fuse-link designed to protect grouped solar strings, photovoltaic cables and associated DC equipment against overloads and short-circuit faults. Part of the Mersen HelioProtection® HP10NH series, it provides dependable full-range circuit protection for commercial, industrial and utility-scale solar installations.
This fuse features a specialised gPV operating characteristic developed specifically for photovoltaic applications. It can safely interrupt the sustained fault currents generated by solar arrays, helping to prevent cable overheating and reduce the risk of damage to combiner panels, inverter inputs and other valuable system components.
With a rated current of 63 A, a rated voltage of 1000 V DC and an industry-standard NH1 body size, the A1028284 is suitable for main protection within grouped photovoltaic string circuits. Its plain blade contacts allow secure clip mounting in compatible NH fuse bases and photovoltaic distribution assemblies.
