NK AGL3-SDT1-120-ENE-TR3-N Large Aperture Ground Fault Relay

Output Type: SPDT Relay (Form C) with auto-reset
Power Supply: 120 VAC
Options: Normally Energized, auto-reset
Setpoint: Tri-set (5, 10, or 30 mA)
Noise Immunity

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 applications.
Sense progressive levels of ground fault in motors or heating systems to detect deterioration prior to catastrophic failure
