PURPOSE: A protection and control assembly is provided to facilitate placement of a mechanical and electrical combination of several electrical devices in cascade in order to make a simple, reliable and economic connection of the protection and control assembly. CONSTITUTION: A protection and control assembly comprises several multipole electrical switch devices each having a box(10,20,30) provided with input side and output side conducting connection strips that project from a horizontal connection area on the input side, and output side respectively, of the box(10,20,30) along a vertical axis and that can be inserted in openings of removable power terminal blocks(40,40',50,50',60). The assembly further includes at least one connecting element(80) that electrically connects the poles of a first and a second electrical device of the assembly. The connecting element(80) is arranged such that it is positioned firstly between the box(10) and a removable power terminal block(40,50) of the first electrical device, and secondly between the box(20) and a removable power terminal block(40',50') of the second electrical device.
