Technical data
Opertae mechanism
main technical parameters of operating mechanism
1.manual energy storage operation force adopts the energy storage handle of the mechanism when the maximum operating force is small 25kgf.
2 over current trip electromagnet:over current release is supplied by current transformer,and the overcurrent release is rated at 5A.
3.current transformer ratio:50/5.75/5,100/5,150/5,200/5,400/5 and 630/5 can be installed according to user needs.
4.surge current protector over current delay time:accordint to user needs can be adjusted to 200ms,400ms,600ms,800ms,1200ms or 3S,user adjustment.
