Tap-off units
Tap-off units are available in a number of versions for different
applications.
BD2-AK1 molded plastic-enclosed tap-off units for up to 25 A
with fuses, miniature circuit-breakers and socket outlets
Features:
• Molded-plastic enclosure, color light gray, similar to RAL 7035
• Transparent cover for the protective elements
• During mounting and removing of the tap-off units, a load
switching capacity of AC-22B up to 400 V is reached
• An anti-rotation feature prevents incorrect mounting
• Power pick-up through silver-plated lyra-shaped contacts
• Cables can be introduced from three sides
• The tap-off unit must be removed from the trunking before the
unit can be opened and the cables connected
• Built-in strain relief
• The connection cables should be supported separately if
required
NSV0_00127
Sheet steel-enclosed tap-off units BD2-AK2 up to 63 A and
BD2-AK3 up to 125 A with cover-integrated switch-disconnector
Features:
• Hot-galvanized sheet steel and cover with powder-coated finish,
color light gray, RAL 7035.
• The tap-off units can be mounted and removed only with their
cover open.
• Switch-disconnector integrated into the cover, switching
capacity at 63 A AC-22B up to 400 V or at 125 A AC-21B,
which ensures that the unit is not live when the cover is open.
• An anti-rotation feature prevents incorrect mounting.
• Cables can be introduced from three sides; use plastic cable
glands with strain relief (not supplied).
• Power pick-up via silver-plated lyra-shaped contacts.
• If the PE conductor is used as a PEN conductor, note that the
PE contact of the BD2-AK3... tap-off units have only half the
cross-section and therefore cannot carry the full rated current.
• The connection cable should be supported separately if
required.
Mounting unit:
For installing devices (e.g. miniature circuit-breakers) in conformance
with DIN 43871, with 8 MW. 1 MW equals a space
requirement of 18 mm. Hinged covers on all tap-off units allow
device operation from outside.

BD2-AK2M2/A323
BD2-AK2 tap-off units up to 63 A
with fuses, miniature circuit-breakers and socket outlets
Features:
• Miniature circuit-breakers can optionally be operated from the
outside (mounting unit with 8 MW; 1 MW = 18 mm)
