Ratings
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.
