What do the terms AC1, AC3 and AC5a mean?
In Intelligent Building Control, different switching capabilities and performance specifications, required by
special applications, have become established in industrial and residential systems. 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 loads, resistive furnaces (relates to switching of ohm-
ic/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 standard EN 60 947-4-1
Contactors and motor-starters
–
Electromechanical contactors and motor-starters
. The standard describes starters and/or contactors that
were originally used primarily in industrial applications.
