Attaching padlocks
1. Move the molded case circuit breaker into the CONNECT, TEST or DISCON position.
The breaker must be in one of these positions before the plastic frame can be pulled out.
2. Pull out the plastic frame.
The crank handle opening is sealed off.
3. Insert padlock shackles through the plastic frame and lock padlocks as illustrated above.
Cylinder lock for protection against unauthorized operation
A cylinder lock can be retrofitted in the right-hand side wall of the draw-out socket. Like with
the padlocks, it can be used to lock a molded case circuit breaker in the CONNECT, TEST
and DISCON positions. The cylinder lock utilizes the locking mechanism of the plastic frame.
This is evident from the way the plastic frame moves into or out of the socket as the cylinder
lock is turned.
Signaling of locked/unlocked status
The locked or unlocked status of a draw-out unit can be signaled electrically. An additional
position signaling switch (3VA9977-0KB00) is inserted in the right side wall of the draw-out
socket for this This switch signals whether the plastic frame described above is in the "IN" or
"OUT" position. For further details, refer to chapter Position signaling switches (Page 244).
