  • Aslo includes stainless steel roller model
  • Contact Form:

NOTE: 

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.
