Abstract

To avoid additional costs, in particular by replacing a switching element too early or by expensive monitoring measures thereof, a control apparatus for controlling a switching element is provided. The control apparatus has an operating unit for setting a load stage at which the switching element can be operated, a control unit for calculating a first numerical value which reflects expected switching cycles of the switching element estimated on the basis of the set load stage and which corresponds to an expected service life of the switching element in dependence on the set load stage, and for determining a second numerical value which reflects effected switching cycles of the switching element. Information from a difference between the first and second numerical values or from a quotient from the second numerical value to the first numerical value during operation of the switching element is provided to a user.
