SL: shutter lock
The SL shutter locks the shutters of the fixed part.
It is possible to lock the upper and lower shutters independently.
This is an accessory available on all the fixed parts and can work with the aid of padlocks with diameters of 4
mm - 0.16", 6 mm - 0.24", 8 mm - 0.32", with a maximum of four padlocks per fixed part (two for the upper
shutters and two for the lower shutters).
NOTE:
The padlocks are at customer's expenses.
DLC: Door opening lock with
the circuit-breaker in closed
position
The DLC prevents the following operations from being carried out:
• opening the switchgear door with the circuit-breaker closed if the circuit-breaker is in fixed version
• opening the switchgear door with the circuit-breaker closed and in connected position if the circuit-breaker
is in fixed version
• closing of the circuit-breaker when the switchgear door is open
Information on the assembly is available on the web site http://www.abb.com/abblibrary/DownloadCenter/,

Fail safe
The fail safe is a device that prevents the removal of the mobile part of a withdrawable circuit-breaker from
the fixed part if the springs are charged.
It is always supplied with UL circuit-breakers.
IMPORTANT:
•
The fail safe device makes undervoltage coil YU unavailable.
•
It is, however, possible not to install the fail safe device, in which case the undervoltage
coil YU must be used.
