Efficient Motor Control for Industrial Automation
Contactors such as the ABB AF38Z control power to three-phase motors by opening and closing the main electrical circuit in response to a low-power control signal. This enables remote switching and integration with programmable controllers, motor starters, relays and automated machinery.
The AF..Z electronic coil interface supports both AC and DC control supplies while reducing holding-coil energy consumption. Integrated surge suppression, voltage-dip tolerance and push-in spring terminals help deliver reliable operation with efficient control-panel installation.
Typical Applications
- PLC-controlled three-phase motor starters.
- Conveyors and material-handling systems.
- Pumps, fans and ventilation equipment.
- Compressors and processing machinery.
- Industrial automation and production systems.
- Electrical control panels and switching equipment.
