Position signaling in the draw-out socket
Several position signaling switches can be inserted in the right side wall of the draw-out
socket. These auxiliary switches are capable of signaling breaker positions DISCON, TEST
and CONNECT. The auxiliary switches also output a position indication signal if the molded
case circuit breaker in the draw-out socket is not in one of the positions specified above. For
information, please refer to chapter Position signaling switches (Page 244).

Padlocks for protection against unauthorized operation

handle opening is mechanically sealed when the plastic frame is in the OUT position.
