Note: 1. Resistive loads have a power factor (cos = φ) of 1.
2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
3. Lamp loads have an inrush current of 10 times the steady-state current, while motor loads have an inrush current of 6 times the
steady-state current.
4. Inrush current: NC: 30 A max.; NO: 30 A max.
