Contactor Selection for Utilization Categories AC-2 and AC-4
Utilization category AC-2 is for breaking the starting current of slip-ring motors, while utilization category
AC-4 is for breaking the starting current of squirrel-cage motors.
Maximum Breaking Current for Categories AC-2 and AC-4
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.
