AF190R ... AF370R reversing contactors are mainly used for directionally controlling 3-phase motor circuits up to 690V AC. These devices include two 3-pole contactors, a mechanical interlock, side-mounted auxilia- 1 ry contacts for electrical interlocking, power bus (see diagram to the left), and are mounted on a backplate.
Note: for mechanically and electrically interlocked devices without power bus, replace the R in the catalog number with an M (ie. AF190R-30-22-13 becomes AF190M-30-22-13).
Note: The higher ratings shown in [brackets] can be achieved through the use of LX.. Terminal extensions. Terminal extensions are included as standard for reversing contactors, but must be purchased separately for mechanically and electrically interlocked devices.
