Mersen introduces new higher amperage 1,500 V DC PV fuses and fuse holders

15 March 2023

Mersen has announced the availability of its new 1,500 V DC HelioProtection 20 mm x 65 mm photovoltaic (PV) fuses and fuse holders, introducing the next level of safety for higher amperage utility scale PV applications.

Mersen’s HP15P series 1,500 V DC HelioProtection fuses are designed specifically to meet higher amperage demands of today’s PV circuits. The fuses have a 20 mm x 65 mm form factor and are designed to handle the harsh cyclical loads and thermal conditions of customers’ highest amperage applications. These 1,500 V DC rated fuses are designed for low minimum breaking capacity capabilities of 1.35 times the fuse ratedSource: MersenSource: Mersen current value, which allows for safe circuit interruption under typical low fault current conditions. In addition to the standard ferrule terminal, fuses are also available with crimp cap terminals for in-line fuse applications. The unique wire crimp terminal permits solderless wire-to-fuse connection for over-mold encapsulation of fuse and wiring.

Mersen’s HP15FHP80 series 1,500 V DC HelioProtection fuse holders for 20 mm x 65 mm PV fuses offers two configurations to fulfill global market requirements. One configuration offers input and output terminals that accept standard PV rated wiring and comb bus bars, providing added versatility for end-use installations. The second accepts wire and bus bar terminations. The body features a high-performance UL 94 V-0 rated polymer material, providing superior flammability rating, with exceptional durability and dielectric withstand properties. HP15FHP80 fuse holders are finger safe (IP20 ingress protection rated) and feature a rotating fuse carrier like the Mersen UltraSafe fuse holders.

Products marked with the HelioProtection brand name have been tested and certified to the latest industry standards for use in PV applications and guarantee the level of performance required by the PV industry. Not only is Mersen the industry benchmark when it comes to standards compliance, the company voluntarily subjects its products to strict quality monitoring backed by extensive electrical, mechanical and climatic tests.
