注:

1、电感性负载: 功率因素=0.4: 时间常数=7msec。

2、 灯泡负载之突入电流为稳定状态电流之10倍。马达负载之突入电流为稳定状态电流之6倍。

3、带弹簧系列产品,操作体的使用范围为从弹簧的前端到弹簧全长的1/3以内。

NOTES:

1. Inductive load has a power factor of 0.4 min.(AC) and a time constant of 7 msec.max.(DC).

2. Lamp load has an inrush current of 10 times the steady-state current,while motor load has an inrush current of 6 times the steady-state current.

3. Product with spring, its usable range of operating part is within one third of the whole spring length from the front end of spring.
