BD2 System — 160 ... 1250 A
Introduction
BD2-AK3 tap-off units up to 125 A
with fuse switch-disconnectors and fuse bases
Features:
• On versions with fuse switch-disconnectors or circuit breakers,
the cover is interlocked with these switches and can
therefore be opened only when they are switched off.
• On versions with fuse bases, the isolator built into the cover
does not disconnect the load. It only removes the voltage from
the installed fuse bases when the cover is opened.
• Terminal bolts for cables.
Device installation unit:
For the installation of devices (e.g. miniature circuit breakers)
based on DIN 43871, with 8 MW. 1 MW corresponds to a space
requirement of 18 mm. Hinged covers on all tap-off units allow
device operation from outside.
BD2-AK02 tap-off units up to 63 A, freely assignable,
with fuses, miniature circuit breaker
Features:
• Miniature circuit breakers can be externally operated if required
(device installation unit with 8 MW; 1 MW = 18 mm)

the cover is interlocked with these switches and can
therefore be opened only when they are switched off.
• Terminal bolts for cables
• Miniature circuit breakers can be externally operated if

BD2-AK2...
BD2-AK02 (AK03) sheet-steel enclosed tap-off units
without cover-integrated switch-disconnector
Features:
• Sheet-steel enclosure, hot-galvanized and powder coated
cover, color light gray, RAL 7035
• The tap-off units can be mounted and removed with their
cover open and closed.
• With the cover open the voltage is still applied to the installed
devices (test facility). Degree of protection IP20 (finger-safe) is
assured.
• Do not mount or remove tap-off units under load.
• An anti-rotation feature prevents incorrect mounting.
• Cables can be infed from 3 directions, use plastic screwed
cable glands with strain relief (not included in the scope of
supply).
• Power pick-up via silver-plated lyre-shaped contacts.
• If the PE conductor is used as a PEN conductor, note that the
PE contact of the BD2-AK03 tap-off units have only half the
cross-section and therefore cannot carry the full rated current.
• The connecting cable should be supported separately if
necessary.
