Note: 1. The above current ratings are the values of the steady-state current.
           2. Inductive load has a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
           3. Lamp load has an inrush current of 10 times the steady-state current.
           4. Motor load has an inrush current of 6 times the steady-state current.
           5. The above ratings are tested under the following conditions.
                 Ambient temperature: 20±2°C
                 Ambient humidity: 65±5%RH
                 Switching frequency: 20 times/min
