2.
The above current ratings are the values of the steady-state current.
3.
Inductive load has a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC). The inductive load rating of the SS-10 is the
same as that of SS-5.
4.
Lamp load has an inrush current of 10 times the steady-state current
5.
Motor load has an inrush current of 6 times the steady-state current.
6.
If the switch is used in a DC circuit and is subjected to inrush current or surge, connect a surge suppressor across the switch.
7.
The electrical rating applies under the following test conditions:
Ambient Temperature = 20±2°C, Ambient Humidity = 65±5%, Operating frequency = 30 operations/minute
