AGL-MAR Series Ground Fault Relay
The AGL-MAR series is a large aperture ground fault relay that offers one of the largest aperture diameters in the industry while maintaining a compact overall profile. Designed for marina applications, the AGL-MAR Series has two jumper selectable trip points for both 30 mA shore power and 100 mA branch circuit applications. Intended for sensing earth leakage, the AGL-MAR Series offers an SPDT Form C relay with auto-reset. The case features integral DIN rail mounting as standard. The AGL-MAR Series Ground Fault Relay monitors all current carrying wires in single or three-phase systems to detect ground faults. It provides a contact output that can operate breakers (MCB or MCCB) equipped with a 120 VAC shunt trip accessory.
PURPOSE BUILT FOR MARINAS
- Designed to satisfy the requirements of article 555 of the 2023 National Electrical Code (NEC).
SETPOINT OPTIONS
- 30 & 100 mA Dual-Set, Jumper Select (defaults to 30 mA when jumper removed) for marina applications.
MOUNTING
- Integral DIN rail mount with spring loaded mounting clips.
- Need a DIN Rail? The optional DIN Rail Kit (DINKIT) includes a 175 mm wide DIN rail and two ends stops.
INSTALLATION
- 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.
LATCHES
- Auto-reset SPDT (Form C Relay) electromechanical relay output.
"ZERO SUM” OPERATING
- AGL-MAR uses “Zero Sum” operating principle to reliably sense imbalance in magnetic fields associated with current leakage to ground.
RESPONSE TIME
- Typical response times for 50 ms to 150 ms.
INTEGRAL BUTTON
- Integral “push-to-test” button with LED indication of contact status.
UL/cUL LISTED
- Accepted worldwide.
Technical Information
Here is what Engineers have to say about our technical expertise...
“Changes to NEC 210.8 B-F have challenged all of us in the industry to find new GFCI solutions. When NK Technologies reached out to us recently, we decided to invest a few hours into meeting with their application experts. Five of our electrical engineering designers attended the session and considered it time well spent. NK Technologies has an in-depth understanding of the new NEC requirements and ground fault products designed to meet them. We are thankful for their time.”
