Main functions The Ekip Touch Trip unit 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.
