AG Series (Solid-state Outputs) by NK Technologies

Product Description

AG Series Ground Fault Detector helps 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.

Note: All AG units offer the 5/10/30 mA Jumper set option and the Tri-set feature. For any other configuration please call Aim Dynamics to order.


Ground Fault Protection Applications
  • Personnel Protection (typically 5 mA)
    • Detects sensitive ground fault conditions, which may be injurious to personnel and processes.
    • Function 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 nuisance 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.
