*What do the terms AC1, AC3 and AC5a mean?
In intelligent installation systems, different switching capacities and performance specifications that are
dependent on the special applications have become established in domestic and industrial installations.
These performance specifications are rooted in the respective national and international standards. The
tests are defined to simulate typical applications, e.g. motor loads (industrial) or fluorescent lamps
(residential).
Specifications AC1 and AC3 are switching performance specifications which have become established in
the industrial field.
Typical application:
AC1 – Non-inductive or slightly inductive load, resistive furnaces (relates to switching of ohmic/resistive
loads)
AC3 – Squirrel-cage motors: starting, switching off motors during running (relates to (inductive) motor load)
AC5a – Switching of electric discharge lamps
These switching performances are defined in the standard EN 60947-4-1 Contactors and motor-starters -
Electromechanical contactors and motor-starters. The standard describes starters and/or contactors that
were originally used primarily in industrial applications.
