NK AGD-SDT-120-ELA-400-LC Ground Fault Sensor - Large Solid-Core

NK AG-LC Series Ground Fault Sensor

Range: 80–400 mA Factory Set
Output Type: Single pole, double throw relay
Power Supply: 120 VAC
Contact Action: Latching normally energized (Fail safe operation)
Trip Point: 400 mA
Case: Large solid-core, panel or DIN Rail mounting
Electromechanical relay output
UL/cUL Approved, CE Pending

The NK AG-LC Series ground fault sensors feature an innovative design ideal for monitoring larger circuits. The 2011 NEC added section 555.3 to require ground fault protection of the main overcurrent device feeding marinas and boat yards. These services are often carrying up to 800 amps; most sensor designs will not allow the conductors to pass through a single sensing ring. By designing a sensor in a large solid-core housing, the conductors will not have to be passed through a separate sensing device like a zero sequence current transformer. This design makes monitoring of larger circuits a breeze, whether to protect boaters or large equipment like amusement park rides or gantry cranes.

Applications:

Monitor Large Machines
Detect leakage to earth before the problem can cause damage.
Water Delivery and Treatment
Keep pumping systems safe and in operation.
Sense faulting stator windings prior to failure.
Generators
Shut down equipment when leakage current exceeds hazardous levels.

Sense Current to Earth in Marinas

Equipment on board a vessel can pass current to earth through water, causing a dangerous condition to swimmers and boaters in fresh water marinas and boat docking facilities. Use a ground fault sensor with a shunt trip breaker to shut off the power when excessive current flows to earth.
