Отводные блоки Международный стандарт производства Siemens

A number of different tap-off units are available, depending on the application.

BD2-AK1 molded plastic-enclosed tap-off units up to 25 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 tap-off units, a load switching ability of AC-22B up to 400 V is achieved.
• An anti-rotation element prevents incorrect mounting
• Energy pick-off over silver-plated lyra contacts
• Cables can be infed from 3 directions.
• It is only possible to open the enclosure and connect the cable if the tap-off unit is removed.
• Integrated strain relief
• Connecting cables must be supported if necessary.

BD2-AK1/CEE165A163

Sheet steel enclosed tap-off units BD2-AK2 up to 63 A and BD2-AK3
with cover separator

Features:

• Sheet-steel enclosure, hot-galvanized, powder coated cover, light gray, RAL 7035
• Mounting and disassembling of the tap-off units is possible only when the cover is 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 element 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).
• Energy pick-off over silver-plated lyra contacts.
• If using the PE conductor as a PEN conductor, please note that the PE contact of the tap-off units BD2-AK3 is only half the cross-section and is therefore unable to carry the full rated current.
• Connecting cables must be supported if necessary.

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. Cover flap(s) on all tap-off units enable external actuation.

BD2-AK2M2/A323

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

Features:

Switch-disconnectors integrated in the cover, switching capacity AC-22B to 400 V, which ensures isolation of the installed devices if the cover is opened.

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, freely assignable,
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 circuit breaker integrated in the cover does not act as an isolating switch, but only ensures isolation of the installed fuse bases if the cover is opened.
• Terminal studs for cables

BD2-AK3X/GSTZ00

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

Features:

• Device installation according to customer requirements in compliance with the requirements of type-tested low-voltage controlgear combinations (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 EN 60715.

BD2-AK2...

Sheet steel enclosed tap-off units BD2-AK02 (AK03)
without cover separator

Features:

• Sheet-steel enclosure, hot-galvanized, powder coated cover, light gray, RAL 7035
• Mounting and disassembling of the tap-off units is possible when the cover is open or closed.
• When the cover is open, voltage is still applied to the built-in devices (test possibility). Degree of protection IP20 (finger-safe) is guaranteed.
• Tap-off units must not be mounted or removed under load.
• An anti-rotation element 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).
• Energy pick-off over silver-plated lyra contacts.
• If using the PE conductor as a PEN conductor, please note that the PE contact of the tap-off units BD2-AK03 is only half the cross-section and is therefore unable to carry the full rated current.
• Connecting cables must be supported if necessary.

BD2-AK02M2/A323

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

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