Both families provide protection and measuring functions related to signals from the installation and are
available in different models and versions.
Ekip Dip is available in three versions:
• Ekip Dip LI
• Ekip Dip LSI

There are four Ekip Touch models available:
• Ekip Touch (LSI, LSIG)

All Ekip Touch models are also available in the version with LCD display for installations situated in
particularly aggressive environmental conditions.
Ekip Dip and Ekip Touch provides the following functions:
1. Measurement : measurement of different quantities, such as: current, voltage, power, energy
2. Protection : depending on the measurements made and the parameters configured by the user, the
Trip unit checks for the presence of alarms and commands circuit-breaker opening if necessary
3. Signalling : management of contacts and communication networks to optimize plant efficiency,
communication among different CB and other functions
The functions are provided both by transducers and actuators inside the circuit-breaker, and by means of
a vast range of external accessories.
