Rated load | Non-inductive | Inductive | ||
---|---|---|---|---|
Resistive load | Lamp load | Inductive load | Motor load | |
250 VAC | 20A | 10A | 8A | 8A |
Note: | 1. | The non-inductive lamp load has an inrush current 10 times steady current. |
2. | The inductive load has a power factor of 0.4 minimum (AC). | |
3. | The motor load has an inrush current 6 times steady current. The above ratings were tested under the following conditions: 1. Ambient temperature: 20±2 °C 2. Ambient humidity: 65±5 %RH 3. Switching frequency: 7 times/min. |
