Fuses

Mersen HP15NH photovoltaic (PV) fuse serie was engineered and designed specifically for the protection of photovoltaic systems. Helio-Protection® HP15NH 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 1XL/2XL/3L sizes having a worldwide acceptance. They are of the gPV type and comply with both IEC 60269-6 and UL 2579 PV standards.
They are available with plain blades, bolted blades for direct mounting with and without striker.

Mersen NH gBat fuse series was engineered specifically for protection of battery systems. They offer full range protection and can protect very small over currents as well as DC fault current up to 150kA. The NH gBat fuses serie covers various ratings in 1000VDC with NH1 and NH2 sizes, and in 1500VDC with NH1XL, NH2XL and NH3L sizes. They are gBat type that comply with new IEC 60269-7 standard for Battery protection. They are available with bolted type blades for direct mounting, or with plain blades.

Mersen's Helioprotection line of fuses are engineered and designed specifically for the protection of strings and combiner boxes in photovoltaic systems.

Mersen offers tried, proven and approved fuses and fusegear complying with the Bristish Standard BS88-2

Mersen is the leader in the French standard cylindrical fuses and fusegear for the protection of low voltage. The brand offers premium components providing space savings combined with low power losses.

The D fuse-system is the first generation of screw fuse-system in the German DIN standard.

The offering encompasses a complete range of NH Switch Fuse Disconnectors and any class of NH power fuses: gG, aM, gTr.

Mersen cable protectors are special purpose limiters which are crimped or bolted to cables to clear and isolate faults quickly, increasing the reliability of service entrance and distribution runs.

Mersen's One-Time general purpose fuses provide low cost protection for feeder and branch-circuits serving lighting, heating, and other non-motor loads. Class K5 fuses will safely interrupt available short-circuit currents up to 50,000 amperes in all ratings up to 600 VAC.

Mersen R-Rated fuses are current-limiting, high interrupting rating fuses intended for the short circuit protection of medium voltage motors and motor controllers.
