The above-mentioned values refer to steady-state-current.
The inductive load refers to power factor = 0.4 in Ac. and a time constant of 7 msec max. in Dc.
Lamp load has an inrush current of 10 times the steady-state current.
Motor load has an inrush current of 6 times the steady-state current.
If the switch is used in a DC circuit and is subjected to a surge connect a surge suppressor across the switch.
