Bar mounted contactors are largely used in the iron and steel industry for traction (rolling stock), electrolysis and hoisting equipment for applications from 63A to 5000A.
The R series contactors are built on a main frame supporting the electro-magnet, the main poles and the auxiliary contacts.
This design offers a great construction flexibility for the standard contactors as well as for the tailor made versions :
variable number of poles acc. to requirements
poles without or with blow-out coils, rated for the current flow in the poles
N.C poles set "make before break" or "break before make" when combined with N.O. poles
large number of standard, timed, adjustable N.O. and N.C. auxiliary contacts
electro-magnets with specific features depending on both the control voltage supply and the utilization characteristics.
