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 Class CC High Interrupting Rating Time Delay and Fast Acting compact fuses, are ideal for protection of smaller motors, control circuits and control transformers up to 30A.

Mersen's compact midget Time Delay and Fast Acting fuses are an excellent choice for "supplementary" protection of lighting, solenoid, motor and transformer circuits.

The most current-limiting UL-Class fuse, Mersen’s Class J fuses provide optimal performance, prevent interchangeability with older code fuses, and save valuable panel space.

Broad range for high voltage fuses for transformer protection.

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

Mersen fuses for the protection of transformers and distribution lines deliver overload and short circuit protection, and are designed to withstand the transformer magnetizing inrush current.
