Combining AC, DC with surge suppression in a single contactor

September 20th, 2013, Published in Articles: Vector

The introduction of the new AF range of contactors completes the ABB portfolio of motor protection and control, which includes thermal and electronic overload relays and manual motor starters. By combining AC, DC with surge suppression in a single contactor and additionally controlling the coil electronically, the company brings a product to the marketplace which offers multiple benefits over the conventional alternatives. These motor control contactors cover applications from 9 A to 1050 A, in all popularly installed sizes. The AF range enables a single contactor coil to handle 100 V – 250 V for both AC and DC applications. Coil energy consumption is reduced by 80%, which allows for the building of smaller panels and the use of more compact transformer designs.
