Field Ground Module
SEL-2664
-
Schweitzer Engineering Laboratories, Inc.
Add the SEL-2664 Field Ground Module to the SEL-300G or SEL-700G to protect all the critical components in your generator with one comprehensive relay. Or, add the SEL-2664 to the SEL-2664S to complete ground fault protection on both the rotor and stator.
