Warranty
•  Standard one-year warranty on all parts
•  The warranty is extended through the addition of the annual maintenance and support contract (nrgSMART-APSC)

Features:

  • Each dual feeds contains eight positions for either bullet-style breakers or TFD fuse holders
  • Five GMT fuses at each of the dual feeds provide ample capacity for distribution to a broad range of components
  • Below the status LED console is A pull-out designation card holder is located below the status LED console
  • Bullet terminals can accept either TFD fuse holders or bullet terminal breakers
  • Single pole, double pole, and triple pole breakers are also supported
  • GMT fuse holders are mounted inverted so that the GMT indicator flag flips downward when tripped, making identification and detection easier, especially on taller racks
  • GMT fuse holders/ sensors are generously spaced for easy grip of fuses and better heat dissipation
