Plugging
The current varies from the maximum plug-braking current to the rated motor current. The making current must be compatible
with the rated making and breaking capacities of the contactor. As breaking normally takes place at a current value at or near the
locked rotor current, the contactor can be selected using the criteria for categories AC-2 and AC-4.
