Note: 1. The above figures are for steady-state currents.
2. Inductive loads have 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. v 4. Motor load has an inrush current of 6 times the steady-state current.
5. The above ratings were tested under the following conditions according.
(1) Ambient temperature:+20±2°C
(2) Ambient humidity: 65±5%RH
(3) Operating frequency:20 operations/min.
