2. Component units
2.1 Drive unit
The drive unit is supplied with one or two motor options for 60, 110 or 220 V DC
and 50, 60 Hz AC.
The motor should be able to charge the springs at 85% of the nominal voltage (IEC).
Figure 2-1. Drive unit.
2.2 Mechanical interlock
The interlocking mechanism prevents a closing operation from being carried out if
the circuit-breaker is already in the closed position or if the operating mechanism’s
closing springs are uncharged or not fully charged, which can occur, for example, if
the closing catch gear is opened by hand or if a mechanical fault occurs in the catch
gear.
