What is the difference between AC1 and AC3 duty contactors?

The difference between AC1 and AC3 contactors is that AC1 contactors are used for general purpose resistive loads but AC3 contactors are used for high inductive, squirrel cage motor switching. The rating of AC3 is lower than AC1. Because AC3 switches high inrush currents.
