INFORMATION
Please note!
The size of the busbar tap-off unit depends on the
variants (see „Technical data“ on page 72)!
The feed of the 125 A version of the busbar tap-off
unit is equipped with a cover disconnector, which
disconnects the tap-off unit from the live busbar
system when the cover is opened. This allows
shockproof working on the installed tap-off unit.
With all other versions of the busbar tap-off unit,
there is no disconnection when the cover is
opened! In this case, a finger-safe design of the
busbar tap-off unit provides protection against
contact.
