Mersen PV Fuses

Mersen (formerly Ferraz Shawmut) is a global manufacturer specializing in electrical power and advanced materials. The company develops innovative solutions for industries such as energy, transportation, electronics, chemicals, pharmaceuticals, and more. For solar applications, Mersen offers electrical components and balance of system solutions for circuit protection, including a wide range of fuses.

Solar fuses, also known as photovoltaic (PV) fuses, protect solar panels, inverters, and control boxes from overcurrent. These fuses interrupt low-fault currents, such as reverse currents and multi-array faults, preventing damage to PV systems.

Mersen’s Photovoltaic (PV) Fuse Series:

  • HP6M Fuse Series (600VDC): Designed to protect PV systems from low fault currents, the HP6M fuse withstands constant temperature and current cycling, enhancing system longevity.
  • HP10M Fuse Series (1000VDC): Developed for industrial rooftop and utility-scale PV systems, this fuse handles continuous temperature and current cycling, ensuring long-term protection.
  • GEN2 HP15M Fuse Series (1500VDC): Built for the high demands of PV systems, this fuse offers enhanced reliability and low minimum breaking capacity, ensuring safe circuit interruption in challenging conditions.
  • HP6J Fuse Series (600VDC): Engineered specifically for DC Recombiner Boxes, this fuse protects 600V PV systems and is optimized for continuous use in extreme conditions.

Mersen’s HelioProtection® line includes fuse bases, blocks, holders, and more, all tested to the latest industry standards. These products guarantee reliable performance in both off-grid and grid-tied PV systems, offering robust protection against faults.
