NK Technologies - AGL Series Large Aperture Ground Fault Sensors

AGL Series, new from NK Technologies, is a large aperture ground fault sensor that offers one of the largest aperture diameters in the industry while maintaining a compact overall profile. Intended for sensing earth leakage in applications up to 600A, the AGL Series offers 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.

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.

Features:

Integral DIN-rail Mount with Spring Loaded Mounting Clips
Setpoint Options Include Factory Adjustable Setpoint from 5mA 100mA or TR3 Tri-Set Models with Field-selectable 5/10/30mA Settings
Finger-safe Terminals for Worry-free Installation and Operation
Aperture Orientation is Perpendicular to DIN-rail, Allowing for Clean and Efficient Wiring and Minimizing Space Between Multiple Components
Choice of Dependable Latching SPST or SPDT (Form C) Electromechanical Relay Outputs
Uses Zero Sum Operating Principle to Reliably Sense Imbalance in Magnetic Fields Associated with Current Leakage to Ground
Typical Response Times from 15ms to 200ms
Integral Push-to-test Button with LED Indication of Contact Status
