Note: 1. The above values are for steady-state currents.
2. Inductive load: Power factor = 0.4; time constant = 7 ms.
3. The lamp load has an inrush current of 10 times the steady-state current.
4. The motor load has an inrush current of 6 times the steady-state current.
The rated values are for testing conducted under the following conditions.
(1) Ambient temperature: 20±2°C
(2) Ambient humidity: 65% ±5%RH
(3) Operating frequency: 20 times/min
