Choose Your Fault Current Rating:

The AC fault current rating should be chosen to exceed the available fault current for the application to avoid product failure. This value can vary widely, but is typically in the range of 3.7kA to 10kA for many applications.

Choose Your Blocking Threshold Rating:

The voltage threshold is the DC voltage at which the Dairyland device switches from the DC blocking mode to the fully conducting mode for safety. Select a threshold that is above the normal cathodic protection voltage difference between the two connection points for the Dairyland device. Note that this value is the voltage between the device terminals (the voltage differential between structures), not the pipe-to-soil voltage. The standard threshold value is -2/+2V, and other options are available.

Choose Your Terminal Configuration:

SSD terminal orientation is in a standard configuration for most applications, as designated by the “-R” catalog number suffix. Choose the alternate terminal orientation when it is desirable to install the SSD via pin brazed attachment of one terminal to the pipe via the Dairyland “Hex Coupling Nut” accessory.
