Abb contactor wiring diagram. The following figure shows the vertical e bypass wiring connection points. The following benefits are provided. The drive which is of bistable type is fitted with an opening and a closing coil. These contactors are made for use in household applications as well as in industrial environments. The magnetic drive adapts perfectly to this type of apparatus thanks to its precise and linear travel. Abb offers a wide variety of discrete medium voltage apparatus to serve oems and to fulfill repair retrofit and upgrade needs.
Refer to the ach550 uh users manual for control connections to the drive.
