5 - Selectivity between ABB SACE circuit-breakers
13 | © 2023 ABB | 1SDH001330R1002 - ECN000297030
5 - Selectivity between ABB SACE circuit-breakers
Foreword
It is possible to obtain selectivity between ABB SACE circuit-breakers (including Emax 2).
There is selectivity in an installation when, in the event of an overload or short-circuit, it is possible to
identify and isolate the point of overload or fault by opening only some circuit-breakers to guarantee
service continuity to the installation.
NOTE: selectivity is recommended in all installations with multiple switchgears or circuit-
breakers connected, for example cascading or in a tree (with a main circuit-breaker on the
supply side, and other circuit-breakers downstream to protect areas on the other side).
Thus, only the circuit-breaker immediately upstream the overload or fault trips, and avoids
opening of the circuit-breakers further upstream.
Types of selectivity
With ABB SACE electronic trip units selectivity can be:
• Current-based selectivity, activated in the event of over-current, and in which the protections of
the trip units are set with different current thresholds, based on the principle the closer the fault
point is to the power supply the greater the current will be.
• Time selectivity, activated in the event of a short-circuit in which the S protection normally trips,
and in which the protections of the trip units are set with different tripping times, so that with
cascading circuit-breakers the circuit-breakers further downstream open before those further
upstream.
• Time-current selectivity, which is a combination of the previously mentioned types, and in which
the protections of the trip units are set so that the tripping times and current thresholds increase
with proximity to the power supply.
• Energy selectivity, which uses current-limiting circuit-breakers, characterized by extremely short
tripping times in the event of a short-circuit to avoid the current reaching the peak value (in the
case of ABB SACE circuit-breakers, for example, all the moulded-case circuit-breakers of the Tmax
series and certain air circuit-breakers of the Emax series are limiters).
• Zone Selectivity, which is an evolution of time selectivity, and in which is a dialog created between
the trip units by means of output and input blocking signals. For more information on Zone
Selectivity with ABB SACE circuit-breakers and in particular Emax 2, see the chapter “1 - Zone
Selectivity" starting on page 138.
Further documents
For each type of selectivity, the protections must be set so that only those circuit-breakers capable of
isolating the overload or fault open, without the rest of the installation being de-energized. Relevant
definitions, operating principles, areas of application, advantages and disadvantages, requirements,
indications for setting the protections and examples are provided in the Technical Application Paper QT1

Families
SACE Emax 2 can be configured to operate with two Trip unit families:
• Ekip Dip with interface via DIP switches
• Ekip Touch with touchscreen display
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
• Ekip Dip LSIG
There are four Ekip Touch models available:
• Ekip Touch (LSI, LSIG)
• Ekip Hi-Touch (LSI, LSIG)
• Ekip G Touch (LSIG)
• Ekip G-Hi Touch (LSIG)
All Ekip Touch models are also available in the version with LCD display for installations situated in
particularly aggressive environmental conditions.
Main functions
The Ekip Touch Trip unit provides the following functions:
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.
