Schneider Electric GAT-12 Ground Fault Relay Class-1

Schneider Electric's Square D GAT-12 Ground Fault Relay Class-1 is a dedicated earth-leakage protection device designed to monitor ground faults in motor-control and distribution panels and provide a fault signal when leakage is detected. It carries a 10 A, 250 VAC contact rating, making it suitable for switching control circuits and interfacing with protective relays in industrial installations. The model is labeled GAT-12 and is marketed as a Class-1 ground fault relay, signaling a focused role in earth-leakage protection. Common applications include motor starters, control panels, and distribution gear where reliable ground-fault monitoring and a defined fault output are required. The fault relay output provides a discrete signal that can be integrated with other protective devices or control-system logic to initiate protective actions, alarms, or interlocks as part of a broader safety scheme.
