Ekip Touch - Protections
1 - Protections - Introduction
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:
1. If the signal measured exceeds the set threshold, the specific protection activates (prealarm and/
or alarm condition).
2. The alarm appears on the display and, after a period of time (timing t
t
), depending on the
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
References
Many of the protection thresholds are displayed in two different quantities: absolute value and relative
value.
The relative value depends on the type of measurement:
Type of protection Reference Description
Current In Nominal current of the
Rating plug
Voltage Un Line-to-line voltage setting
Frequency fn Frequency setting
Power Sn √3 x In x Un
Protections packages
The protections described in the following chapters are grouped into packages, the availability of which
depends on the model and version of the Trip unit, and on their ability to be installed as additional
package:
