    Inrush Current N.C: below 24A, N.O: below 12A
    Notes:
  • 1.Inductive load has a power factor of 0.4 min.(AC) and a time constant of 7 msec.max.(DC).
  • 2.Lamp load has an inrush current of 10 times the steady-state current,while motor load has an inrush current of 6 times the steady-state current.
