Application
AF 50 ... AF 750 contactors are mainly used for controlling 3-phase motors and generally for controlling power circuits up to 690 V a.c. or
220 V d.c. / 600 V d.c. The contactors can also be used for many other applications such as bypass, capacitor switching, lighting, d.c. power
circuits...
The AF... contactors are fitted with an electronic coil interface which accepts a wide control voltage range, on a.c. 50/60 Hz or d.c. supplies.
The same contactor can accept various supply voltages according to different countries where the final machine will be used or some
fluctuation in the control voltage due to the local supply or network.
The AF... contactors are also fully suitable for operation in a.c. or d.c. control circuit liable to voltage interruptions or voltage dip risks.
Description
The AF 50 ... AF 750 3-pole contactors are of the block type design.

• Electronic control:
The contactors are fitted with an electronic interface that very precisely controls the voltage to the coil. The electronic control circuit always
works using d.c. current through the coil and in a.c. operation the current is rectified before being applied to the coil. To achieve the levels of
the currents required for making and holding respectively, the voltage is pulsed across the coil with the aid of a transistor. The pulsing also
implies that the current in the coil can be optimally regulated all the time relatively independently of the voltage level. The function is controlled
by a specific integrated circuit developed by ABB.
