CurrentWatch™ EGFL Series Ground Fault Sensors
Large Aperture Ground Fault Sensors with
Auto Reset
Instructions Publication P51995
Effective July 2017
Introduction
The CurrentWatch™ EGFL Series is a
family of large aperture ground fault
(earth leakage) ground fault sensors.
Ground fault sensors help protect people,
products, and processes from damage
by ground fault conditions by monitoring
current-carrying conductors in grounded
single- and three-phase delta or wye sys-
tems. The EGFL Series is available with
mechanical relay outputs.
The EGFL Series with mechanical relays are available in solid-core
housings with a choice of N.O. or N.C. SPST latching relays and a
SPDT Form C relay with auto-reset. All models are designed with
a “tri-set” option which provides three field adjustable setpoints: 5,
10, or 30 mA jumper-selectable.
ote:N This manual only covers EGFL Series models listed in the above table.
This installation manual does not cover EGFL Series models with latching
relays. (For that installation manual, see P51994.)
Quick Install Guide
The below steps can be followed to quickly install a CurrentWatch
EGFL Series sensor.
1. Run all current carrying conductors through sensor window, using an
auxiliary current transformer if conductors do not fit.
2. Mount the unit by snapping sensor onto DIN rail. (To remove at a
later time, insert a flat-head screwdriver into the tab, and gently pry
the tab up to disengage the spring mount locking tabs from the rail.)
3. Connect output and power wiring:
a. Use up to 14 AWG copper wires,
b. Ensure power and load matches those shown on the sensor
label.
4. Test the unit:
c. Pressing the “TEST” button will test the sensor’s internal cir-
cuits,
d. CAUTION: The output and any connected loads will switch dur-
ing the test process.
Installation and Mounting
Considerations for all EGFL Series sensors…
•
Run wire to be monitored through the aperture (opening) in the
sensor body, making sure all wires are oriented so that current
flows in the same direction (see “Principal of Operation” section).
•
These sensors can be located in the same environment as
motors, contactors, heaters, pull-boxes, and other electrical enclo-
sures.
•
Mounting can be done in any position or hung directly on a wire
with a wire tie.
•
Be sure to leave at least one in. (2.54 mm) distance between sen-
sor and other magnetic devices.
For more detailed installation and wiring instructions, see reverse
later in this document.
Principal of Operation
Under normal conditions, the current in one wire of a two wire load is
equal in strength but opposite in sign to the current in other wire. The
two wires create magnetic fields that cancel, a condition known as “Zero
Sum Current”. If any current leaks to ground (Ground Fault), the two
currents become unbalanced and there is a net resulting magnetic field.
The EGFL Series sensor detects this minute field and changes the out-
put state. This concept extends to three phase systems such as 3-wire
Delta and to 4-wire Wye.

Wiring
Use up to 10 AWG copper wire and tighten terminals to 5.3 in.-lbs /
0.60 N·m maximum torque. See diagram below.
Power
Connect power wiring to terminals 1 and 2. The input supply volt-
age is not polarity sensitive. Be sure the power supply matches the
power requirements.
Output
Connect output wiring to the appropriate terminals. Note: Circuits
connected to output terminals will be energized when the “TEST”
button is pushed.
Operation
To test operation, gently press the TEST button. This simulates a
fault and tests the internal switching circuits. You should observe
the following operation. CAUTION: Any circuit connected to the
sensor will be operated.

Power Supply Notes
All low-current ground-fault sensors are sensitive devices that
require reasonable care in system design to avoid false trips caused
by high electrical noise levels. Keep in mind that the best way to
reduce noise in a system is to suppress it at its source.
•
Keep the sensor power isolated from noisy circuits.
•
Do not power the sensor with the same circuit that switches con-
tactors or other high current inductive loads.
System Grounding
Good design practice and code require that all AC power systems
be grounded. The EGFL Series sensors are designed to work on
grounded AC power systems. They may not operate properly on
ungrounded systems.
