The option R provides 2 independent static
contacts which operate when the current
exceeds adjustable pickup limits (two
independent limits lc1 and lc2 adjustable
from 0.8 to
1
x the long time setting.
•
when
the
current exceeds the limit lc1 (or
lc2) the contact R1-R2 (or R3-R4) closes,
following an inverse time characteristic
a
•
when the current drops below the limit lc1
(or lc2) the contact R1-R2 (or R3-R4) opens
with constant time delay (3 seconds)

These contacts can be used for load
shedding, alarms, indications, etc ...

(option
F
and J)
In addition to the mechanical fault indicator,
long time, short time/instantaneous and
ground fault trips are indicated separately.
Fault Indications
differentiate the 3
causes of tripping : overload, short circuit
and ground fault if any.
Option F provides LED's indicators located
on the front face of the control unit
Option J provides LED's indicators and opto
decoupled outputs (terminals 612-622-632)
Alarm Indication
(option F only) indicates
before the breaker trips that the long time
pickup has been exceeded.
A
separate control source is required. Fault
indications are maintened as long as the
control voltage is provided. When the
control voltage is considered as unreliable,
auxiliary power module (AD) and battery
pack module
(BAT)
may be added to
preserve memory.
