Dairyland SSD 3/1 Solid-State Decoupler

The Dairyland SSD-3/1 Solid-State Decoupler is engineered to offer unidirectional DC blocking while providing a safe, low-impedance path for AC fault currents and lightning transients. Designed for use in cathodic protection and grounding systems, the SSD-3/1 series is ideal where current flow is predominantly in one direction. These units protect infrastructure from corrosion interference while maintaining electrical safety compliance. With DC blocking thresholds available at 2.0V, 3.7V, and 5.0V, and an AC fault current rating up to 100kA, the SSD-3/1 delivers reliable, rugged performance in demanding environments.
