Square D CAD323GD Contactor, Solid State Overload Relay, 0.5

The Square D CAD323GD is a contactor with an integrated solid state overload relay, classified under Relays > Solid State Overload Relays and Circuit Breakers, Fuses & Protection. It's a motor-protection component that combines switching and overload sensing in one package — the contactor handles the load current, and the solid state overload relay monitors for thermal overload conditions and trips the contactor when the motor draws excessive current over time.
