4. Arc Sensors
The EAFR-01 comes without a connection cable.
Connection cable installation at site is simple. The cable
connectors are located beneath the covers of the sensor
and can be conveniently detached for fastening the sen-
sor wires. The covers will be reattached after installing the
wires. Cable connectors are located at both ends of the
sensor for series connecting a maximum three sensors in
one line (see Figure 8).

4.2 Arc Light Fiber Optic Loop Sensor (Plastic)
EAFR-06
The EAFR-06 is an arc light fiber optic loop sensor. The
EAFR-06 fiber is a plastic fiber optic cable. EAFR-06 sen-
sors can be ordered in pre-manufactured lengths of 10,
15, 20, 25, 30, 35, 40 m (33 to 131 ft). The EAFR-06 loop
sensor fiber optic cable should be distributed throughout
the protected switchgear cells. The EAFR-06 is not rec-
ommended to be cut and/or spliced on site. If accidental
breakage of the loop sensor occurs, Eaton recommends
replacing the loop sensor. Contact your nearest Eaton rep-
resentative for more information.
The fixed light sensitivity of the EAFR-06 sensor is 8,000
Lux. The sensor does not require user settings. The loop
sensor's detection radius is 360 degrees (see Figure 10).

4.3 Arc Light Fiber Optic Loop Sensor (Glass) EAFR-07
The EAFR-07 is an arc light fiber optic loop sensor. The
EAFR-07 fiber is a robust fiber optic cable providing practi-
cally unlimited bending radius. The EAFR-07 contains hun-
dreds of glass fiber drains covered by a plastic tube making
it extremely strong. EAFR-07 sensors can be ordered in
pre-manufactured lengths of 10, 15, 20, 25, 30, 35, 40,
45, 50 m (33 to 164 ft). The EAFR-07 loop sensor fiber
optic cable should be distributed throughout the protected
switchgear cells. The EAFR-07 is not recommended to be
cut and/or spliced on site. If accidental breakage of the
loop sensor occurs, Eaton recommends replacing the loop
sensor. Contact your nearest Eaton representative for more
information.
The fixed light sensitivity of the EAFR-07 sensor is 8,000
Lux. The sensor does not require user settings. The loop
sensor's detection radius is 360 degrees (see Figure 11).
