Iii.Model meaning
4.Structural features
fully assembled structure,lightweight and beautiful,can be assembled at will,for unlimited extension.
it can be equipped with model fn12-12 compressed air load switch and combination electrical appliances,as well as model fzn25-12 vacuum load switch and combination electrical appliances.
small size,maintenance-free,three-phase linkage structure,with obvious isolation fracture.
load switch,combination of electrical appliances,flexible installation,can be left and right side,formal,inverted(FZN25 not inverted).
manual and electric operation,remote control function.
with perfect and reliable mechanical linkage and interlock device,the function of"five prevention"is fully achieved.
A.when the load switch closes,the ground switch cannot close and the front door cannot be opened;
B.When the load switch is on,the ground switch can be closed.When the ground switch is on,the front door can be opened;
C.When the ground switch closes,the load switch cannot close,and the front door plate can be opened;
D.When the ground switch is on,the load switch can be on and off,and the front door plate cannot be opened;
E.No matter the load switch is at the closing or opening position,the electromagnetic lock controls the front door plate when the cable enters the wire under the cable,and it cannot be opened.(except emergency unlock with special key)
the load switch adopts linkage protective insulation valve or transparent insulation cover to cover the live contact and ensure personal safety.
positive operation and maintenance,reliable wall installation.
the front door is equipped with observation window,which can clearly observe the working condition of the components inside the cabinet.
