Ever higher demands are being placed on the installations in modern residential, commercial, and industrial buildings. Supply and operational safety are the most important aspects in their planning. In addition, there is flexibility of use, low environmental impact, the lowest possible overall costs, as well as the possibility of integrating renewable energies. Increasing automation and the growing volume of data are also increasingly coming to the fore.
Taking all these factors into account can exploit the full potential of a building in terms of economic efficiency, added value, and the fulfillment of modern technical requirements. The wiring of a building is therefore of immense importance. Weidmuller AITB installation terminal blocks facilitate and accelerate the planning and execution of uniform and clear wiring of the complete building installation as well as the required control cabinets.
The PUSH IN technology of the AITB modular terminal blocks enables the tool-free connection of solid conductors and fine-stranded conductors with wire-end ferrules
AITB installation terminal blocks have an NT disconnector with test tap for quick and safe performance of functional tests
The AITB installation terminal blocks are designed for space-saving wiring in standard distribution boards and facilitate fast and safe installation
Progressive automation requires more space in the control cabinet. A consistent product and system portfolio is advantageous for electrical power supply and distribution – from the supply in the distribution cabinet to the final circuit. Our comprehensive range of high current terminal blocks for power feed enables convenient wiring of conductor cross-sections between 35 and 185 mm², even in confined spaces. This makes power feed into switchgear and cabinets simple, efficient, and space-saving.
The additional connection for the cross section from 50 mm² up to 185 mm² enables a separate voltage tap. One possible use is as an emergency power supply upstream of the main switch. The lever mechanism enable tool less wiring of flexible conductors.
Large-area marker tags direct attention to an external voltage applied. Fixation of the flash markers in the connection areas of 35 mm² to 185 mm² also prevents circuitry in the live state. This ensures greater safety for man and machine.
A standardized 2.0 mm diameter test tap allows easy and fast testing. Uniform accessories guarantee use in the cross-section ranges from 1.5 mm² to 185 mm² and ensure a streamlined portfolio of accessories.
The cross connections could be installed tool less by latching the wire inside the connection point. The electrical contact will be given with or without a cable inside the connection point. Thanks to their special design, they could be easily identified with or without any conductor connection.
Because the requirements for electrical power distribution in modern buildings are growing, the planning complexity of building infrastructures is also increasing. The desire for safety and flexibility over the entire life cycle requires a targeted selection of all connection components. AITB installation terminal blocks are the right solution here. They combine high efficiency and safety with low wiring time requirements.
Current and voltage transformers are used in power transmission and distribution primarily for safety and measuring functions. Klippon® Connect instrument transformer terminal blocks of the TTB range meet the specific requirements of these two critical applications. With the new terminal block series, the wiring of current and voltage transformers can be carried out particularly easily and safely, even within complex circuits. Operating errors during testing are also avoided, which increases system availability and extends the life cycle of the entire switchgear. In this way, the specific requirements of the users are optimally fulfilled.
The complete provision of data in the Weidmüller Configurator (WMC) enables a particularly simple selection of safety-critical accessories as well as safe and rational product configuration.
The combination of disconnecting lever, short-circuit bridge and lever link in a single system guarantees that the secondary wiring of a current transformer is short-circuited before the longitudinal disconnection takes place. This "make before break" contact is designed for up to four terminals.
All function-relevant and safety-relevant components are captively connected to the terminal block. This increases the reliability of the current transformer and voltage converter circuits during installation and maintenance work.
The integrated combi-foot enables the fast and flexible mounting of the instrument transformer terminal blocks on common G32 and TH35 mounting rail profiles. This means that retrofitting can take place without the cost-intensive replacement of the mounting rails.
Careful planning and installation of protective functions in the building protects life and limb of users, occupants, and visitors. However, earthing and shielding have different tasks in personal and system safety. Earthing is primarily installed to protect life and limb. Shielding ensures the proper functioning of an electrotechnical system as well as its electromagnetic compatibility. Equipotential bonding includes all measures to neutralize electrical voltages. The wide range of our A-Series protective conductor terminal blocks and KLBÜ shield connections make it easy to implement your installations.
Ensures simple handling and proper connection with permanent contact pressure as a result of the spring effect.
Simply swiveled onto the busbar by hand - retrospective if necessary.
Changes in diameter (flow) of the conductor is compensated for by the elastic behavior of the clamping yoke for flexible adjustment to the cable diameter.
A wide range of fastening methods can be used for the installation of shield connection clamps.
Installation wiring places high demands on the design of terminal blocks: On the one hand, economical and compact solutions are required here. Simple handling and clarity also need to be guaranteed. The reason: there is little space for wiring in installation distributions and small distribution boards. Our AITB installation terminal blocks for building installation are optimally suited for these requirements. The PUSH IN connection technology enables a particularly compact design with great clarity. This enables simple and safe wiring of your building infrastructure.
In the Weidmuller Configurator (WMC) you can digitally plan, assemble, and directly order complete terminal rails – including accessories. You can also create complete parts lists and installation instructions for production. This prevents failures and saves costs.
The continuous cross-connection channels of our modular terminal blocks AITB increase flexibility and save wiring time. Structures in the 400 V three-phase system can be cross-connected easily and conveniently with the phase conductors L1, L2, and L3.
The neutral conductor can be separated from the busbar quickly and easily with a screwdriver. A clearly visible status display indicates the current contact position of the disconnecting slide. This reliably prevents operating errors.
Our modular terminal blocks AITB are regularly inspected by independent test centers to ensure maximum product safety within the switchgear. This is immediately shown by the corresponding test marks on the products and product labels.
Use the Weidmuller Configurator to quickly and easily configure and request our components. The tool supports continuous engineering workflows from planning with E-CAD systems to documentation.
