SPECIFICATIONS
Nominal voltage : 6-69 kV
Starting criteria :

Line energised for at least 5
seconds followed by a stepped
instant current increase of 6, 12,
25, 60 or 120A
OR

absolute phase current exceeding
250, 500, 750, 1000A
AND

a three-phase disconnection of the
line within 5 sec.
Required fault duration: > 60ms (20ms on
request)
Reset criteria:
1)
Voltage/Current reset after 30sec.
(Can be disabled)
The minimum required current for start/reset,
depends on the settings of di/dt or threshold

*) Maximum load current defines the level
for saturation where di/dt sensor cannot
detect the programmed increase.
NB! If I(load) > Max load

It may start
flashing without any fault!
2)
Timer reset 2h, 6h, 12h, or 24h.
3) Manually (KBN-4 reset tool/ magnet)
Line diameter: 5 – 36mm
Current consumption:
Non-activated: LT-110Eµ: 30-40µA
LT-110Eµr: 300 µA
Activated (flashing): 4 mA.
Battery: 3.6 V 16,5Ah type KBB-11
Recommended battery replacement approx.
every 10 years (5 years for LT 110Eµr) or
every 1500 operational hours, whichever
comes first.
Indication:
5 High intensity LED’s; 1 green, 3 red/amber
and 1 yellow (“Low battery”)
Fault-permanent
: All 5 LED’s flash every 5 sec.
(10 sec after 12 hours)
Fault-transient : 1 green LED flash (every 5/10s)
Low battery : Yellow LED flash every 10s to
indicate < 20% capacity left
Intensity: > 12 Lumens

Weight: 460 grams.
Standards: Conform to IEC 68-2.
Tested according to:

EN 61000-6-3 Generic standard –
Emission industrial environments

LT-110Eµr w/integr.Short Range Radio:
The radio transmit a status telegram to the
Collector (ComTroll 110C/115C or other)
every 10 sec; containing Permanent or
transient faults, low battery warning and
Heart Beat.
Frequency: ISM band, 2.4 GHz
Output: 1mW (0dBm), range: up to 20m*)
Line Of Sight (LOS).
*) Margin = 20dB, with a Receiver
sensitivity = -90dBm (=CmT 110C/115C).
Longer distance may be achieved by taken
special action when mounting and
positioning the antenna and the indicators.
