AG-LC Series Ground Fault Sensor: New Large Solid-Core Design Ideal for Monitoring Larger Circuits

AG-LC-Series-Ground-Fault-SensorSAN JOSE, CA – July 12, 2019 – NK Technologies announced the AG-LC Series, a new ground fault sensor that makes it easy to monitor larger circuits. The 2011 NEC requires ground fault protection of the main over-current device feeding marinas and boatyards, where these services often carry up to 800 amps. Most sensor designs do not allow the conductors to pass through a single sensing ring, requiring a separate sensing device such as a zero-sequence current transformer. The AG-LC Series resolves this issue with an innovative large solid-core housing design that provides ample space for multiple conductors to pass easily through one sensing window.

Key applications include:

  • Monitoring large machines: Detecting leakage to earth before the problem can cause damage
  • Water treatment and delivery: Keeping pumping systems safe and in operation
  • Generators: Shut down equipment when leakage current exceeds hazardous levels

AG-LC Series highlights include:

  • Electromechanical relay output provides both normally open and normally closed contacts
  • Compatible with most automation and control systems
  • Externally powered – choice of fail-safe or standard operation
  • Simple field setpoint adjustment
  • Adjustable time delay
  • DIN Rail or panel mount
