If the molded case circuit breaker is not in any of the defined positions, the switching position
indicator displays the word UNBLOCK on a white background. In this position, the molded
case circuit breaker is either off (position OFF, contacts open) or tripped (position TRIP,
contacts open). The breaker main contacts cannot be closed with the breaker in the
UNBLOCK state.
Depending on the position of the molded case circuit breaker in the draw-out unit, the
outputs of the position signaling switches assume one of the following states:
Signal "Draw-out unit locked / open"
①
Slot for position signaling switch for signal "Draw-out unit locked / open"
