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