2 - Guide to the product choice

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.
