AGL Series Ground Fault Relays

Product Description

AGL Series are large aperture ground fault relays that offer one of the largest aperture diameters in the industry while maintaining a compact overall profile. Intended for sensing earth leakage in applications up to 300 A, the AGL Series Large Aperture Ground Fault Relays offer a choice of N.O. or N.C. latching relays or an SPDT Form C relay with auto-reset. Enclosure features integral DIN rail mounting as standard and optional noise immunity coatings for applications in harsh EMI/RFI environments.


Ground Fault Protection Applications
  • Replace bulky two-piece sensor solutions which require
    separate CTs or relay modules.
  • Use with shunt trip breakers to provide total ground fault
    protection to sensitive machine electronics.
  • Detect ground faults in resistance/impedance heating,
    industrial automation and control, theatrical lighting,
    portable power distribution, and snow melt/heat trace
  • Sense progressive levels of ground fault in motors or
    heating systems to detect deterioration prior to catastrophic


Ground Fault Protection Features

  • Broad Range of Options to Match Application Needs
    • N.O./N.C. Solid-state switch.
    • Normally energized or normally de-energized contacts.
    • Noise Immunity option for use in EMI/RFI sensitive environments.
  • Setpoint Options Maximize Ease-of-Use
    • Field-selectable 5 mA, 10 mA or 30 mA setpoints on the AG# “Tri-set” model makes user adjustments fast, sure and convenient.
  • Compatible with Standard Equipment
    • Applicable on single and three- phase systems.
  • Ranges to Suit Your Needs
