A capacitive block for electrical equipment includes a housing, at least one capacitive element having a first end housed in the housing and a second end, which is opposite to the first end and which extends out of the housing, an end-stop being fixed to the second end of the at least one capacitive element, and at least one spacer, which butts against the end-stop, so as to determine the distance between the second end of the at least one capacitive element and a bottom of the housing.
