PV Fuses and Fuse Holders

Mersen’s range of 2000VDC photovoltaic (PV) fuse series is designed specifically to meet higher amperage demands of today’s PV circuits. Mersen’s 22x85mm form factor is designed to handle the harsh cyclical loads and thermal conditions of our customers’ highest amperage applications. These 2000VDC rated fuses are designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated 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 (CC option) permits solderless wire-to-fuse connection for overmold encapsulation of fuse and wiring. Protect your off-grid or grid tied PV system from unexpected line faults using Mersen’s HelioProtection® fuse line.

Mersen’s 1500VDC HelioProtection fuse holders for 10/14x85mm gPV fuses introduce the next level of safety for Utility scale photovoltaic applications. The HP15FHM32 fuse holders are also IP20 finger safe, with a rotating fuse carrier like the Mersen UltraSafe® fuse holders. The US15M1HEL fuse holders are finger safe up to an IP20 grade of protection, and feature a pull out, pivoting fuse carrier. All bodies feature high performance UL 94 V-0 rated polymer material, providing superior flammability rating, with exceptional durability and dielectric withstand properties.

The HP15FHM32 series input and output terminals accept standard PV rated wiring and comb bus bars, providing added versatility for end-use installations.The US15M1HEL is designed with terminals to accept standard stock bus bar eliminating the need for custom combed bus bar, saving cost, time and simplifying installation.

Mersen HP6M photovoltaic (PV) fuse series was engineered and designed specifically for the protection of photovoltaic systems. Its enhanced fuse construction makes it ideal for constant temperature and current cycling withstand adding to system longevity. The 600VDC rated HP6M, designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays. Protect your off-grid or grid tied PV system from unexpected ground faults and line faults using Mersen's HelioProtection fuse line.

Mersen’s HP6J photovoltaic (PV) fuse series was engineered specifically
for DC Recombiner Boxes in the protection of 600VDC photovoltaic
systems. Its enhanced construction makes it ideal for continuous
temperature and current cycling withstand adding to system longevity.
The 600VDC rated HP6J designed for low minimum breaking capacity
capabilities of 1.35 times the fuse rated current value allows for safe circuit
interruption under typical low fault current conditions produced by PV
arrays. Protect your off-grid or grid tied PV system from unexpected
ground faults and line faults using Mersen’s HelioProtection® fuse line.
