By means of the union of contactors MC with the blocks of
preload AC9 or AC50, we obtain the special contactor for
the connection of three-phase cpower capacitors , ***oiding
therefore the high currents of connection of the capacitor-
sand the use of additional chokes.
The block of preload resistence c***ists of three auxiliary
contacts of preclosing, along with resistance (two by pha-
se) through which the capacitors are preconnected to the
network, cushioning therefore the tips of connection current.
Once the preload resistance h***e reduced the current tips
that take place in the connection of the capacitor, takes pla-
ce the automatic opening of the auxiliary contacts with the
objective of not h***ing unnecessary losses.
