Operating principle The protection functions are available with all Ekip Touch models and versions.

Each protection is associated with a different signal (current, voltages, frequencies, powers, etc) but the
operating principle is the same:
If the signal measured exceeds the set threshold, the specific protection activates (prealarm and/

or alarm condition).
The alarm appears on the display and, after a period of time (timing t

protection parameters set, can convert into a trip command (TRIP) transmitted to the internal
Trip Coil of the CB.
NOTE:
• if the signal measured drops below the set threshold before the trip time has elapsed, Ekip
Touch quits the alarm and/or timing status and returns to the normal operating condition
• all protections have a default configuration: check the parameters and change to suit the
installation requirements before putting into service

The relative value depends on the type of measurement:
