The base of types with threaded stud and
d
= 91 mm is fully insulated (the lengths
l
and
l

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 notes on mounting given on page 168.
Screw terminals with UNF threads are available upon request.
