Guide to the product choice
1 - List for Emax 2 selection
Foreword
The circuit-breaker must check and protect , in case of failure and malfunction, the installation components
that are connected to it. To perform this function, Emax 2 circuit-breakers offer a series of options, that can
be selected by the user according to the particular requirements of the installation.
For a good design, the main characteristics the components must be selected with the greatest care.
In order to help the design engineers in selecting the Emax2 circuit-breakers, a sheet is provided below
containing the main selection criteria for air circuit-breakers. This sheet can be completed (in whole or in part)
by the design engineer to guide subsequent design choices and can be used by the client for work contracts.
Besisdes, this sheet is a useful tool for rapid configuration in CAT selection software.

2 - 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 “Specific applications" starting on
page 156.
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 1SDC007100G0205 "Low
voltage selectivity with ABB circuit-breakers".
