5 - Protections
Operating principle All the protections present in the electronic trip units with a display (Ekip Touch, Ekip Hi-Touch, Ekip G Touch,
Ekip G Hi-Touch) have a delay time before entering alarm state and tripping the circuit-breaker.
The duration of the delay depends on the parameters set: threshold, time, curve. Depending on the current
read by the trip unit, there are two possible behaviours:
• Current above the protection threshold, persistent alarm condition, the trip unit will open the circuit-breaker.
• Current below the protection threshold, alarm condition and delay interrupted.
The protection threshold relates to different parameters, according to the type:
Type Reference
Current Nominal current of the rating plug (In).
Voltage Rated voltage set (Un)
Frequency Frequency set (fn)
Power Current multiplied by rated voltage (Sn = √3 * In * Un)

The protection forces the tripping time to 1 second in two cases:
• if according to the calculation the time is less than 1 second.
• if the fault current is greater than 12 In.
(2)
Activatable with protection MCR= Off.
(3)
Activatable with protection I= Off.
(4)
The protection automatically deactivates in the event of a connection error of 1 or more sensors, or if the
measured current is higher than a maximum value:
• 8 In (with I4 ≥0.8 In).
• 6 In (with 0.5 In ≤I4 < 0.8 In).
• 4 In (with 0.2 In ≤I4 < 0.5 In).
• 2 In (with I4 < 0.2 In)
(5)
Detailed description in the Design Engineer's manual.
(6)
If the presence of sensor S.G.R. is activated, G protection adjustment is replaced by the Gext item in the
Advanced section. Both the G and Gext items are available with Ekip Hi-Touch and Ekip G Hi-Touch.
(7)
Available in the Circuit-Breaker Settings menu.
(8)
Locking Function available via Ekip Connect.
(9)
For all the UL versions the maximum time allowed by the trip unit is 0.4 seconds. If a higher value is set, the
trip unit signals the error and forces the parameter to 0.4 seconds.
(10)
For all the UL versions the maximum threshold allowed by the trip unit is 1200 A. If a higher value is set, the
trip unit signals the error and forces the parameter to 1200 A.
(11)
The current thresholds do not manage the trip, but only the signal.
Neutral Adjusting of the neutral setting is used to customize the L, S and I protections on the Neutral pole with a
control factor different from the other phases.
Represented as a percentage, it defines the multiplication factor applied to the tripping thresholds of the
protections (example: 50%= the tripping threshold of the neutral is half the phase threshold).
NOTE: adjust the neutral setting only with four-pole or three-pole circuit-breakers with external
neutral.

, as shown in the example.
(3)
Valid tolerances with steady-state energized trip unit or trip unit energized by auxiliary power supply, tripping time ≥ 100 ms, temperature and
currents within operating limits. If these conditions are not guaranteed, the tolerances in the table that following these notes are valid.
(4)
In the presence of auxiliary power supply, you can select all the thresholds. In self-supply mode the minimum threshold is limited to: 0.3 In (with In
= 100 A), 0.25 In (with In = 400 A) or 0.2 In (for all other sizes).
(5)
The MCR time is the time for which the protection remains active after circuit-breaker closing. Tripping time, not adjustable, as for protection I.
(6)
Startup can be activated only with the function set to fixed time.
(7)
For the startup functions, the specified time is the period during which the protection with the different threshold remains active, calculated from
the moment the startup threshold is exceeded.
(8)
With t4 = Instantaneous, the maximum tolerance is 50 ms.

The trip unit accepts the I21 and Ks2 parameters provided that their product is greater than or equal to 0.6 Hz / s: Ks2 * I21 >= 0.6 Hz / s.
(5)
The tripping threshold of the current for voltage values between Ul2 and Uh2 is calculated by performing the linear interpolation between the
thresholds Uh2 and I21 (first point on the line) and Ul2 and Ks2 * I20 (second point on the line). Ithreshold = [I10 * (1 - ks2) * (Umeasured - Uh2)] / (Uh2 -

(6)
The tripping threshold of protection RQ2 is calculated by the intersection of the 2 straight lines formed by Q24 and Kq (Pthreshold = Qmeasured * Kq +
Q24) and from Q25 and Kq2 (Pthreshold = Qmeasured * Kq2 + Q25). If the constants Kq and Kq2 are set to 0, the highest threshold will apply (see the
sample graph in the chapter on the RQ protection).
