Earth-fault detector GFD

Ground Fault Detector Detects ground faults by sensing the vector sum of the current flowing through a three-conductor cable. Choice of three reset options (secondary voltage, load current, or time) to meet various application needs. Split-core sensor installs on three-phase cables without opening the primary. Large reflective red target display is easy to see both at night and during the day. Submersible, vinyl-coated sensing core. Stainless steel hardware and UV-stabilized materials ensure long product life. Thousands of SEL GFDs in service today help customers around the world quickly locate ground faults.
