Ratings
Note: 1.
The above current ratings are for steady-state current.
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.
4.
Motor loads have an inrush current of 6 times the steady-state current.
5.
For those with indicators, refer to the following rated voltages.
