Footnotes

  1. The starting current of motors of more than standard horsepower may require the use of fuses with appropriate time delay characteristics.
  2. Std.—Using fast acting one time fuses. Max.—Using dual element time delay fuses. (Non-fusible switches have max rating unless noted.)
  3. Use outer switching poles.
  4. If used on corner grounded delta systems, install neutral and use outer switching pole for ungrounded conductors.See data bulletin 2700DB0202 for additional information.
  5. 480 Vac 1 Phase HP = 3 Std, 7.5 Max
  6. 10 Std, 15 Max
  7. 480 Vac 1 Phase HP = 5 Std, 20 Max
  8. 25 Std, 30 Max
  9. 480 Vac 1 Phase HP = 10 Std, 30 Max
