|The LV28 DRY-REED terminal, made in a polyamide self-extinguishing container, can be mounted, either on EN50022, (OMEGA) section or on EN50035, (DIN 1 (CEI 17.18) section in the three versions “a” – “b” – “c”, (shown in Figure 1), with spacing of 18 mm and 23 mm. In addition, the especially designed hook device of the terminal enables LV28 relays to be rotated 180° with respect to the position of the section. The connection points of the coil end with removable IP20 terminals with screw tightening, with the capacity of 2.5 mmq, while the terminals of the Reed Relay contact can be welded, faston 2.8×0.5 mm, or with removable IP20 terminals with screw tightening, with the maximum capacity of 2.5 mmq. The terminals are marked with 2 pre-cut plates 14 mm x 6 mm.|
