Tap-off units are available in a number of versions for different applications.

BD2-AK1 molded plastic-enclosed outgoing units up to 25В A, freely assignable,
with fuses, miniature circuit breakers and socket outlets

Features:

• Molded-plastic enclosure, light gray, similar to RAL 7035
• Transparent cover for the protective devices
• When mounting and disassembling the outgoing units, a load switching ability of AC-22B up to 400 V is achieved
• An anti-rotation feature prevents incorrect mounting
• Power pick-up through silver-plated horseshoe 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 connecting cables should be supported separately if required

BD2-AK1/CEE165A163

Sheet steel enclosed outgoing units BD2-AK2 up to 63В A and BD2-AK3 up to 125 A with cover separator

Features:

• Sheet-steel enclosure, hot-galvanized, powder coated cover, light gray, RALВ 7035
• The tap-off units can be mounted and removed only with their cover open.
• Switch-disconnector integrated into the cover, switching capacity at 63В A AC-22B up to 400В V or at 125В A AC-21B, which ensures that the unit is not live when the cover is open.
• Unintentional closing of the cover can be prevented by fitting a padlock
• 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 horseshoe contacts.
• If using the PE conductor as a PEN conductor, please note that the PE contact of the outgoing units BD2-AK3 is only half the cross-section and is therefore unable to carry the full rated current.
• The connecting cables should be supported separately if required

Device installation unit:

For the installation of devices (e.В g. miniature circuit breakers) based on DINВ 43871, with 8В MW. 1 MW corresponds to a space requirement of 18 mm. Hinged covers on all tap-off units allow device operation from outside.

BD2-AK2M2/A323

Outgoing units BD2-AK2 up to to 63В A
with fuses, miniature circuit breakers and socket outlets

Features:

• Miniature circuit breakers can be externally operated if required (device installation unit with 8 MW; 1 MW = 18 mm)

BD2-AK2X/CEE325S33

BD2-AK3 tap-off units up to 125 A
with fuse switch-disconnectors and fuse bases

Features:

• On versions with fuse switch-disconnectors or miniature circuit breakers, the cover is locked with these and can therefore only be actuated if the switching block is 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

BD2-AK3X/GSTZ00

Tap-off units BD2-AK2 up to 63 A and BD2-AK3 up to 125 A
equipped to customer specifications

Features:

• Device installation to customer specification in compliance with the requirements for type-tested low-voltage switchgear and controlgear assemblies (TTA). For configuration, quote and delivery ask your contact in your local Siemens office.
• Device fixture on holed plates, module strip or mounting rail according to ENВ 60715

BD2-AK2...

BD2-AK02 (AK03) sheet-steel enclosed tap-off units
without cover-integrated switch-disconnector

Features:

• Sheet-steel enclosure, hot-galvanized, powder coated cover, light gray, RALВ 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 possibility). Degree of protection IP20 (finger safety) 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 horseshoe 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 cables should be supported separately if required

Tap-off units BD2-AK02 up to 63В 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)

BD2-AK02M2/A323

Outgoing units BD2-AK03 up to 125В A
with circuit breakers, fuse switch-disconnectors, fuse bases,
miniature circuit breakers and fuse switches

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.
• Terminal bolts for cables
• Miniature circuit breakers can be externally operated if required (device installation unit with 8 MW; 1 MW = 18 mm)

BD2-AK03X/L...
