Protective Devices and Electronics

Our protective devices and electronic protection products offer you comprehensive protection against short circuits, ground faults, overloads and overvoltage for vulnerable equipment and systems. Take advantage of our wide range of products to minimize failures and production downtime and ensure optimal protection of your hazardous equipment.

Our compact ECBs save space and offer the best possible protection against short circuits and overloads. With a large number of available configurations and features, as well as a very good price–performance ratio, WAGO offers you the right product, whatever your application.

For incipient ground faults, the ground resistance signaling module per IEC 60204-1 provides greater safety through fully automated preventive maintenance.

In addition, our overvoltage protection products reliably protect electrical equipment and systems against high voltages (e.g., varistor terminal blocks).
