NH PV Fuses

Blade and Bolt-on 1000Vdc NH PV Fuses

Bussmann series NH size 1, 2 and 3 PV fuses are specifically designed for protecting and isolating array combiners/re-combiners, disconnects and inverters.

These 1000Vdc PV fuses are capable of interrupting low overcurrents associated with faulted PV systems (reverse current, multi-array fault) while offering the highest current density with two unique mounting options:

  • The traditional blade version for use with a fuse block provides quick, tool-less replacement for easier maintenance.
  • The bolt-on version with common hole centers easily integrates into standardized busbar designs for component reduction and improved assembly time.

Standard features

  • Compact size saves enclosure space for greater design flexibility
  • Bolt-on version features common hole centers for standardizing busbar designs across the 63-400 amp range
  • Bolt-on version eliminates the fuse block to reduce installation time and components
  • Industry-leading low power loss provides greater efficiency and lower operating temperature
  • Global agency standards simplify designs for worldwide markets
  • Dual indication feature and optional microswitches make system monitoring easier
  • Optional microswitches 170H0236 or 170H0238 and BVL50.
  • Compatible with Bussmann PV NH base range (see data sheet no. 720149)
