	The utilisation categories for contactors/ starters is defined for the type of load the contactor/ starter is going to feed. Utilisation Category AC-1 is used for non-inductive or slightly inductive loads, eg resistance furnaces Utilisation Category AC-3 is used for squirrel cage induction motors with duty cycle of starting, switching off the motors when running (it does not involve plugging and inching operation) __________________ Atlas Shrugged - JGD
