NK AG3-SDT1-120-DEN-TR3-N Ground Fault Detectors

NK AG3-SDT1-120-DEN-TR3-N Ground Fault Detector

AG Series Ground Fault Detectors help protect people, products, and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded single- and three-phase delta or wye systems.

Ground Fault Protection Applications

• Personnel Protection (typically 5 mA)
  • Detects sensitive ground fault conditions, which may be injurious to personnel and processes
  • Functions as sensor and alarm trigger when part of an overall ground fault protection system
• Equipment Protection (typically 10 mA or 30 mA)
  • For applications where personal protection is not the primary concern, higher setpoint capability helps eliminate nuiscance tripping while still providing adequate ground fault detection to protect machine electronics
• Regulatory
  • Meets requirements as stipulated by governmental and industrial regulatory groups for ground fault sensing

AG Series Outputs

AG Series with Solid-state Outputs – offer the benefit of reliable, long-lasting solid-state switches. Sold-state design provides unlimited switch operating life, superior resistance to shock and vibration, zero off-state leakage, high switch speeds and high input-output isolation. Available in solid-core case with screw terminals.

AG Series with Mechanical Outputs – are available in solidcore cases with a choice between a N.O. or N.C. SPST latching relay and a SPDT Form C relay with auto-reset. All mechanical models can be ordered with factory-set, field-adjustable setpoint or with a “Tri-set” option, which provides three factory-set setpoints. A noise immunity option is available for applications in harsh EMI/RFI environments.
