The following conditions must be fulfilled in carrying out mechanical interlocking:
· If the interlocking mechanism is attached to one of the interlocking pins, the weight of the directly attached
movable part to the interlocking pins shall not exceed 0.35 kg. Exception is the single phase LD series,
where the attached movable part shall not exceed 0.1 kg. If both interlocking pins are used, the sum of the
attached weights shall not exceed 0.35 kg or 0.1 kg for single phase (Figure 33).
· If the attached part is joined with a lever mechanism, the weight (including directly moved parts) shall be
decreased in proportion to the lever (Figure 34).
· If the interlocking mechanism is directly attached with the synchronizing shaft the moment of inertia of the
attached mechanism shall not exceed 4.3 x 10
-4
kg/m² (1.2 x 10 kg/m² for single phase series).
If both stub shafts of the synchronizing shaft are used, the sum of the attached moments of intertia shall not
exceed 4.3 x 10
-4
kgm² or 1.2 x 10
-4
kgm² for the single phase series (Figure 35).
· For manual tripping a force of up to 250 N may be applied to the interlocking pins. However no static force shall
be applied (Figure 36).
· It is not allowed to perform electrical trip/close commands while blocking the interlocking pins or the synchronizing
shaft mechanically.
