Ekip E-LSIG
Main characteristics:
Q available for XT4 in three-pole and four-pole versions;
Q protections:
– against overloads (L): 0.4...1xIn adjustable protection threshold, with adjustable time trip
curve;
– against short-circuits with delay (S): 1...10xIn adjustable protection threshold, with adjustable
time trip curve;
– against instantaneous short-circuits (I): 1...10xIn adjustable protection threshold, with instan-
taneous trip curve;
– of the neutral in four-pole circuit-breakers;
Q measurements:
– available from 0.2xIn in Vaux mode and starting from 0.5xIn in self supply mode; external
current or voltage transformers are not required. See table for ranges and accuracy;
– Currents: three phases (L

, L

), neutral (Ne) and earth fault;
– Voltage: phase-phase, phase-neutral;
– Power: active, reactive and apparent;
– Power factor;
– Frequency and peak factor;
– Energy: active, reactive, apparent, counter;
Q setting:
– manual setting using the relative dip-switches on the front of the trip unit, which allow the
settings to be made even when the trip unit is off;
– electronic setting, made both locally using Ekip T&P or Ekip Display accessory and via remote
control, by means of the dialogue unit Ekip Com. The electronic setting have a wider range
and a thicker regulation step.
Use of electronic setting allows other functions to be activated:
- function for protection against earth faults (G): 0.2..1xIn adjustable protection threshold,
with a time constant trip curve;
- over voltage protection 0.5…0.95 Un with a time constant trip curve;
- under voltage protection 1.05…1.2 Un with a time constant trip curve;
Q LED:
– LED on with steady green light indicating that the trip unit is supplied correctly. The LED
comes on when the current exceeds 0.2xIn;
– red LED for each protection:
- L: LED with steady red light, indicates pre-alarm for current exceeding 0.9xI
1
;
- L: LED with flashing red light, indicates alarm for current exceeding setted threshold;
- fixed LED MAN/ELT show the kind of active parameters;
- LSIG: LED with steady red light, shows that the protection has tripped. After the circuit-
breaker has opened, connect the Ekip TT or Ekip T&P accessory to find out which protec-
tion function tripped the trip unit;
– the trip unit is equipped with a device that detects the eventual opening solenoid disconnec-
tion thanks to the simultaneous blinking of all the LED;
Q test connector on the front of the release:
– to connect the Ekip TT trip test unit, which allows trip test, LED test and signalling about the
latest trip happened;
– to connect the Ekip T&P unit, which allows the measurements to be read, the trip test to be
conducted, the protection functions test to be carried out, electronic setting of the protection
functions of the trip unit and of the communication parameters;
Q self-supply from a minimum current of 0.2xIn up; measurements starting from 0.5xIn;
Q the three-pole version can be accessorized with external neutral current transformer and external
neutral voltage connection kit;
Q with the addition of the Ekip Com in the circuit-breaker, you can:
– acquire and transmit a wide range of information via remote control;
– accomplish the circuit-breaker opening and closing commands by means of the motor
operator in the electronic version (MOE-E);
– know the state of the circuit-breaker (open/closed/trip) via remote control;
– setting the configuration and programming the unit, such as the current thresholds and the
protection function curves.
