With the AF contactor range, instead of different contactors for different line voltages, ABB manages to reduce the number of contactor coils to four:
- - 24-60VAC 50/60HZ or 20-60VDC
- - 48-130VAC 50/60HZ or 48-130VDC
- - 100-250VAC 50/60HZ or 100-250VDC
- - 250-500VAC 50/60HZ or 250-500VDC
Thus, the total number of product variations is reduced by up to 90%, which in turn simplifies customer logistics, while also reducing storage and administration costs.
The AF contactor ensures crisp operation in unstable networks and prevents shutdowns caused by voltage fluctuations. The electronic system in the AF contactor continuously monitors the current and voltage applied to the coil. The contactor always operates safely in an optimized state and without being noisy.
Coil and power consumption are reduced by up to 80%, allowing for reductions in temperature, size of control transformers and size of cabinets.
Additionally, AF contactors have built-in surge suppression. Conventional technology recommends the use of an external surge arrester, an accessory that can cost as much as half of the price of the contactor. With AF technology, surges are managed by the contactor and never reach the control circuit.
