Tollerances in case of:
– self-powered trip unit at full power;
– 2 or 3 phase power supply.
In conditions other than those considered, the
following tollerance hold:
Ekip M-I
Main characteristics:
Q only available for XT2 in three-pole version. It is normally used in combination with a thermal relay
and a contactor for motor protection;
Q protections:
– against instantaneous short-circuit (I): protection threshold adjustable from 6...14xIn, with
instantaneous trip curve;
Q manual setting by means of the special dip-switches positioned on the front of the trip unit,
which allow its adjustment even with the trip unit off;
Q LED:
– fi xed green LED which indicates correct operation of the trip unit; the LED lights up for a cur-
rent over 0.2xIn;
Q Test connector positioned on the front of the trip unit:
– for connection of the Ekip TT test unit, which allows the trip test and the LED test;
– for connection of the Ekip T&P unit, which allows the measurements to be read, to carry out
the trip test and to carry out the protection function test;
– self-supply starting from a minimum current of 0.2 x In.
