The base of types with threaded stud and d = 91 mm is fully insulated (the lengths l and l1 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.
Dimensions and weights
Dimensions are also valid for 2-pad solution and low-inductance design.
Packing
For ecological reasons the packing is pure cardboard.
