Battery contactors for industrial trucks
AFS Series contactors are designed for use with electric vehicles in material handling. They are mainly used as motor contactors and much demanded as replacement and new contactors for most leading brands of trucks
The DC NC contactors are suitable for switching resistive, capacitive and inductive loads. They come with double-break contacts which are weld resistant and hard wearing and ensure high conductivity.
