The functions they are intended to perform are as
follows:
1. The breaker is held mechanically trip free during
racking. The latch check switch is also held open, thus
pre-venting any electrical close signal from closing
the breaker.
2. The breaker is permitted to be withdrawn in the safe
mode (breaker open/springs discharged) when
bringing the breaker to the Withdrawn position or to
the Connected position.
The two outlined functions are accomplished by pushing
up the tripper rollers.
When required, the customer is responsible for
providing the proper interfaces with the Series 29
opening/ closing floor trippers. Refer to the Series 29
outline.

for specific details as to exact
locations and the amount of travel associated with each
trip-per.
MOC Operator
The MOC (Mechanism Operated Control) switch
operator is coupled to the pole shaft. As a breaker
closes, the operator moves to change the MOC switch
contact position. MOC switch contacts operate in the
same manner as the auxiliary switch contacts in the
breaker. The MOC switch operator is located on the
bottom of the Series 29 breaker element (Figure
6-8
).
