Siemens SENTRON 3WL10 Manual page 129

Each of the locking devices listed here is available in versions for the fixed-mounted and
withdrawable breaker versions.
● Fixed-mounted breaker:
To mount the modules on a fixed-mounted breaker, the side wall must be modified so
that the main contact position can be mechanically transmitted to the interlocking module.
It is important whether the circuit breaker is mounted on the wall or on the floor. In one
case (wall mounting), the modification must be made to the side part; in the other (floor
mounting), the base support must be modified. The necessary modification is made in the
factory before delivery for the configuration ordered by the customer. This requires the
correct article number.
● Withdrawable breaker version: Here, the modules can be directly mounted on the guide
frame; modification of the circuit breaker side wall is not required.
Locking mechanism to prevent opening, direct
These accessories prevent the control panel door from being opened in the following cases:
● Fixed-mounted breaker: The circuit breaker is in the CLOSED switch position.
● Withdrawable breaker: The circuit breaker is in the CONNECT guide frame position and
the CLOSED switch position.
The mechanical interlocks and locking devices must not be used together with the following
accessories:
● Auxiliary switch AUX 15Q
● Withdrawable breaker: Direct locking mechanism to prevent opening of the control panel
door
If Bowden cables are used, the maximum length is 2 m.
The locking device also locks out the open circuit breaker when the control panel door is
open.
