On the steel frame are mounted bearing epoxy-resin isolators which fix contact elements.
The upper bell insulator (1) supports, on its outside, the main upper terminal (2) and, on its inside, the fixed contact (3), consisting of the contact fingers (4) and of the contact rod (5). With the switch disconnector in open position, the bell insulator is shut by a hinged shutter (20), actuated by the shaft (13) of earthing switch together with the blades of same, thus achieving a complete and reliable segregation of the live parts. This is the most prominent feature of the LBS series ISARC, covered by the patent n. 26743A-79 VEI.

The lower insulator (6) supports the lower terminal (7), the moving contact cylinder (8) and the guiding tulip contact assembly (9).
