NK AGL2-NCR1-24U-LA-LAM - Ground Fault Relay, Factory Set Trip Point 100mA

AGL Series Large Aperture Ground Fault Relays 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 offers a choice of N.O. or N.C. latching relays or an SPDT Form C relay with autoreset. Case features integral DIN rail mounting as standard and optional noise immunity coatings for applications in harsh EMI/RFI environments.

Ground Fault Relay 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.

Ground Fault Relay Features

Setpoint Options Maximize Ease-of-Use

• Setpoint options include factory-adjustable setpoint from 5 mA -100 mA or "TR3 Tri-Set" models with field-selectable 5/10/30 mA 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 15 ms to 200 ms.
• Integral "push-to-test" button with LED indication of contact status.

DIN Rail Mount

• Integral DIN rail mount with spring loaded mounting clips.

UL/cUL and CE Approved.

• Accepted worldwide.
