Mersen launches Gen2 of its HelioProtection series HP15M solar fuses

November 15, 2021 – Mersen’s next generation of HelioProtection series HP15M solar fuses have been designed and tested to more stringent standards, says the manufacturer, while keeping the same form factor, electrical performance, and pricing.

The fuse series is designed specifically to meet the severe temperature and current cycling of a solar PV system. These 1500VDC-rated fuses are designed for low minimum breaking capacity capabilities of 1.35x the fuse-rated current value, which allows for safe circuit interruption under typical low-fault current conditions.

In addition to the standard ferrule terminal, these fuses are also available with Crimp Cap terminals for inline applications. The unique wire crimp terminal (CC option) permits solderless wire-to-fuse connection for overmould encapsulation of fuse and wiring.
