Circuit-breakers for power distribution
Electronic trip units
Ekip I
Main characteristics:
Q usable with the XT2 and XT4 circuit-breaker in the three-pole and four-pole versions;
Q protections:
– against instantaneous short-circuit (I): adjustable protection threshold from 1...10xIn, with
instantaneous trip curve;
– of the neutral in four-pole circuit-breakers:
- for In*100A in the OFF or ON positions, 50% and 100% of the phases can be selected;
- for In<100A, neutral protection is fi xed at 100% of the phases and disableded by user;
Q manual setting using the relative dip-switches, which allow the settings to be made even when
the trip unit is off;
Q LED:
– LED lit with a steady green light indicating that the trip unit is supplied correctly. The LED
comes on when the current exceeds 0.2xIn;
– LED with a steady red light, indicating that protection I has tripped; red LED light on connect-
ing Ekip TT or Ekip T&P accessories after circuit-breaker opening for “I protection” interven-
tion;
– Ekip I is equipped with a trip coil disconnection protection device that detects whether the
opening solenoid has disconnected. Signalling is made by the red LED fl ashing;
Q test connector on the front of the trip unit;
– to connect the Ekip TT trip test unit, which allows trip test, LED test and signalling about
latest trip happened;
– to connect the Ekip T&P unit, which allows the measurements to be read, the trip test to be
conducted and the I protection function test to be carried out;
Q self-supply from a minimum current of 0.2xIn up.
