The Mersen B1028285, catalogue reference HP10NH1GPV80, is a high-performance photovoltaic fuse-link designed to protect grouped solar strings, photovoltaic cables and DC power distribution equipment against overloads and short-circuit faults. As part of the Mersen HelioProtection® HP10NH series, it provides reliable full-range protection for modern photovoltaic systems operating at up to 1000 V DC.
Featuring a specialised gPV operating characteristic, this fuse is engineered specifically for photovoltaic applications where conventional fuse-links are not suitable. It safely interrupts the sustained fault currents generated by solar arrays while helping protect expensive inverter equipment, combiner boxes and DC distribution circuits.
With a rated current of 80 A, an NH1 square-body format and plain blade terminals, the B1028285 is ideal for commercial rooftop systems, industrial photovoltaic installations and utility-scale solar farms requiring dependable overcurrent protection.
Photovoltaic systems generate sustained DC fault currents that require protective devices specifically engineered for solar applications. The Mersen B1028285 provides full-range gPV protection, enabling it to respond effectively to both overloads and short-circuit faults while maintaining reliable protection for valuable photovoltaic equipment.
Its NH1 format, 1000 V DC rating and low power losses make it suitable for commercial rooftops, industrial installations and utility-scale renewable energy projects where dependable circuit protection is essential.
