COMMUNICATION AND CONNECTIVITY 4/23

Ekip CI
This module is an accessory for the Ekip M Touch LRIU trip unit and is needed when the circuit-breaker
and the contactor must work in conjunction with each other. In this way the higher number of operations
of the contactor are used instead of the circuit-breaker. When the trip unit is set in Normal mode (default
mode) by means of the Ekip CI module the contactor is activated in one of the protection trips (excluding
I and G protections); if the Heavy mode is set the trip unit directly opens the circuit-breaker. The auto- 04
reset function allows the actuation status of the Ekip CI to reset automatically after the contactor has
tripped owing to the L function, once an adjustable time from 1 to 1000s has elapsed. Auto-reset can
— occur only in Normal mode. The BACK UP function is available and deals with situations whereby an
Ekip CI
opening command transmitted to the contactor via module Ekip CI has not been successful. In this
case, the Ekip M Touch LRIU trip unit sends an opening command to the circuit-breaker after waiting a set
time Tx. The actuation time of the contactor given by the manufacturer must be considered when the Tx
time delay setting is entered. The function is active with an auxiliary supply.

Rating Plug
The rating plugs are field interchangeable from the front on all the trip units and the protection thresh-
olds can be adjusted according to the actual rated current of the system. This function is particularly
advantageous in installations that may require future expansion or when the power supplied needs to be
limited temporarily (e.g. mobile Gen Set). For the XT7 and XT7 M special rating plugs are also available for
residual current protection against ground faults combined with a suitable external toroid. For the XT5,
— the following rating plugs are available for the two versions of Ekip Touch (400A and 630A).
Rating Plug On the Ekip Touch 400 it is not possible to install the 500A and 630A rating plugs.
