Threaded stud mounting
The base of types with threaded stud and d = 91 mm is fully insulated (the lenghts I and l
1
are in-
creased 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".
Screw terminals with UNF threads are available upon request.
