  • NH size 1, 2 and 3 are compact to save enclosure space for greater design flexibility.
  • Industry-leading low power loss provides greater efficiency and lower operating temperature.
  • Dual indication feature and optional microswitches make system monitoring easier.
  • Bolt-on version features common hole centers for standardizing busbar designs across the 63-400 amp range.
  • Bolt-on version eliminates the need for a fuse block, reducing installation time and components
