The base of types with threaded stud and d = 91 mm is fully insulated (the lenghts I and l1 are increased by 0.5 mm in these cases). For types with threaded stud and d ≤ 76 mm the base is not
insulated. Also refer to the mounting instructions in chapter "Capacitors with screw terminals –
Accessories" on the internet.
