Ekip G-LS/I
Main characteristics:
Q available for XT2 and XT4 in the three-pole and four-pole versions. Allows the protection against
overloads to be extensively adjusted;
Q protections:
– against overloads (L): I
1
=0.4...1xIn adjustable protection threshold, with inverse long-time trip
curve;
– against delayed short-circuits (S): 1...10xIn adjustable protection threshold, with adjustable
trip curve (as an alternative to I protection);
– against instantaneous short-circuits (I): 1...10xIn adjustable protection threshold, with instan-
taneous operating time (as an alternative to S protection);
– neutral, in four-pole circuit-breakers, can be set in the OFF, ON positions at 50% or 100% of
the phases;
Q 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;
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 setted threshold;
- L: LED with flashing red light, indicates alarm for current exceeding setted threshold;
- LS/I: 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;
– Ekip G-LS/I is equipped with a trip coil disconnection detection device that detects whether
the opening solenoid has disconnected. Signalling is made by all the LEDs flashing simulta-
neously;
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;
– for connecting the Ekip T&P unit which allows the measurements to be read and the trip test
to be carried out;
Q thermal memory which can be activated by Ekip T&P;
Q self-supply from 0.2xIn up.
