PV Fuses and Fuse Holders

The innovative and comprehensive Modulostar® range of Mersen fuse-holders.
CUS101HEL series are specially designed for the protection of PV systems.
Modular fuse-holders are finger-safe under IEC and UL standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). Modular fuse-holders CUS101HEL are available in 1 pole, with or without visual blown fuse indicator.
Modulostar® range is made of tough and durable thermoplastic material.

They are especially recommended to be used in combination with Mersen fuse-links HP6M and HP10M.

Mersen HP10NH photovoltaic (PV) fuse series was engineered and designed specifically for the protection of photovoltaic systems. Helio-Protection® HP10NH fuse links are designed for the protection of cables in a PV group of chains when a short circuit occurs in a panel (main fuse category). This HelioProtection® main fuse range enlarges our PV fuse links offering on a size having a worldwide acceptance. They are of the gPV type and comply with both IEC 60269-6 and UL 2579 PV standards.
They are also available with bolted type blades for direct mounting.

Mersen’s HP15G photovoltaic (PV) fuse series was engineered
specifically for PV module ground fault protection of photovoltaic
systems. Its enhanced construction makes it ideal for continuous
temperature and current cycling withstand adding to system
longevity. The 1500VDC rated HP15G, designed for low minimum
breaking capacity capabilities of 1.35 times the fuse rated current
value, allows for safe circuit interruption under typical low ground
fault current conditions produced by PV arrays. In addition to the
standard ferrule terminal, these products are 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 ground faults and string faults using Mersen’s
HelioProtection® fuse line.

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.
