Why Choose the Mersen HP10M15 Photovoltaic Fuse?

The Mersen HP10M15 is a compact and dependable gPV photovoltaic fuse link developed specifically for protecting solar PV circuits against overcurrents, ground faults and line faults. As part of the proven Mersen HelioProtection® HP10M series, it is engineered for the distinctive low fault-current conditions found in photovoltaic arrays.

Rated at 15 A and 1000 V DC, the HP10M15 provides full-range photovoltaic circuit protection for individual PV strings, combiner boxes and inverter input circuits. Its low minimum breaking-current capability allows safe interruption from approximately 1.35 times the fuse rated current, helping protect cables and valuable solar equipment under fault conditions.

The HP10M15 features a compact 10.4 × 38.1 mm cylindrical body with tin-plated copper ferrule terminals for clip mounting. Its enhanced construction withstands continuous temperature and current cycling, supporting long service life in grid-connected and off-grid photovoltaic installations.

Key Advantages

  • Purpose-designed gPV fuse protection for photovoltaic systems.
  • 15 A current rating suitable for PV string circuits.
  • 1000 V DC voltage rating for high-voltage solar installations.
  • Low minimum breaking-current capability for photovoltaic fault conditions.
  • High 50 kA breaking capacity.
  • Enhanced construction withstands repeated temperature and current cycling.
  • Compact cylindrical format for space-efficient installation.
  • Ferrule terminals enable straightforward clip mounting.

Key Features

  • Mersen HelioProtection® HP10M series.
  • 15 A rated current.
  • 1000 V DC rated voltage.
  • gPV photovoltaic fuse characteristic.
  • 10.4 × 38.1 mm cylindrical fuse body.
  • Tin-plated copper ferrule terminals.
  • Clip-mounted installation.
  • Low minimum breaking current of approximately 1.35 × In.
  • Suitable for grid-connected and off-grid PV systems.
  • RoHS-compliant construction.

Reliable Protection for Photovoltaic String Circuits

Photovoltaic arrays can continue producing DC current whenever sufficient light is available. Ground faults, line faults and reverse currents can therefore place cables, modules and connected equipment at risk unless correctly coordinated overcurrent protection is installed.

The Mersen HP10M15 is designed to interrupt the relatively low fault currents associated with solar arrays while withstanding continuous operating-current and temperature cycles. This makes it suitable for dependable string protection in industrial rooftop, commercial and utility-scale photovoltaic systems.

Typical Applications

  • Photovoltaic string circuit protection.
  • PV combiner and array junction boxes.
  • Solar inverter DC input protection.
  • Industrial rooftop photovoltaic systems.
  • Commercial solar power installations.
  • Utility-scale photovoltaic arrays.
  • Grid-connected and off-grid PV systems.
