Why Choose the Mersen H1025393 160 A Photovoltaic Fuse?

The Mersen H1025393 is a high-performance gPV photovoltaic fuse link designed to protect high-voltage solar power circuits against overcurrents and short circuits. Developed for demanding photovoltaic installations, this square-body fuse provides dependable protection for PV arrays, combiner boxes, inverter inputs and associated DC equipment.

With a rated current of 160 A and a rated voltage of 1200 V DC, the H1025393 is suitable for high-power commercial, industrial and utility-scale solar systems. Its gPV operating characteristic is specifically engineered to interrupt both low-level and high-level fault currents that may arise in photovoltaic applications.

The fuse features an NH121-size square body with robust blade connections for installation in compatible fuse bases and switchgear. Its reliable construction helps protect valuable photovoltaic components while supporting safe system operation, reduced downtime and long-term installation performance.

Key Advantages

  • Purpose-designed gPV protection for photovoltaic circuits.
  • 160 A rated current for high-capacity solar installations.
  • 1200 V DC voltage rating for modern high-voltage PV systems.
  • Full-range protection against low and high photovoltaic fault currents.
  • Square-body construction provides reliable performance in demanding environments.
  • NH blade format enables secure installation in compatible fuse equipment.
  • Helps protect PV cables, combiner boxes and inverter input circuits.
  • Suitable for commercial, industrial and utility-scale solar applications.

Key Features

  • Mersen photovoltaic fuse link.
  • 160 A rated current.
  • 1200 V DC rated voltage.
  • gPV full-range photovoltaic fuse characteristic.
  • NH121 fuse size.
  • Square-body fuse construction.
  • Blade terminals for mounting in compatible fuse bases.
  • Designed for high-voltage DC circuit protection.
  • Suitable for photovoltaic array and inverter protection.
  • Reliable operation under repeated solar installation load cycles.

Reliable Protection for High-Voltage Solar Circuits

Photovoltaic arrays continue producing DC current whenever sufficient light is available. Fault currents can therefore persist unless they are safely interrupted by correctly selected protective devices. A gPV fuse is engineered specifically for the electrical behaviour of photovoltaic systems, including relatively low fault-current levels that conventional industrial fuses may not clear effectively.

The Mersen H1025393 helps isolate faulty sections of an installation before excessive current damages cables, modules, combiner equipment or inverter inputs. Its 1200 V DC rating makes it suitable for high-voltage solar architectures where dependable isolation and coordinated circuit protection are essential.

Typical Applications

  • Commercial photovoltaic installations.
  • Industrial rooftop solar systems.
  • Utility-scale solar farms.
  • PV array combiner and re-combiner boxes.
  • Solar inverter DC input protection.
  • Photovoltaic cable and feeder protection.
  • High-voltage renewable energy distribution systems.
