The operation of the CB takes place by means of a
current energy for “Open” and “Close” operations
by a capacitor bank. As a result, the auxiliary
of the pole. The MABS card analyses and indicates
sensor information and given operating orders.
The MABS card repeats this indication through
auxilliary relays so that it is available for external
use.
