From planning and installation to operation and maintenance, this requires first-class installation
solutions that ensure clarity and ease of service in every installation situation.
For this purpose,
Weidmüller has developed the new A-Series AITB installation terminals, which meet the wiring and connection
requirements in installation distributors according to VDE. With the new terminal block systems, the
multiplication of potentials in a 3-phase system can be easily realised via cross-connections.
Practical connection system across all cross-sections
The new terminal block systems are equipped for every task. The uniform busbar position even makes it
possible to combine different terminal block products and connection systems in one overall system. For
large cross-sections – e. g. N conductors – the side screw terminal connection is available.
Terminal blocks
with convenient PUSH IN connection systems are used to collect and distribute the potentials. With this,
even stranded wire conductors can be connected by simply pressing the coloured pusher.
Simplified testing routines
The prescribed regular tests include measuring the insulation resistance of all conductors to earth in
accordance with VDE 0100-718 and DIN VDE 0100-
482. The neutral conductors must also be tested individually
and electrically disconnected for this purpose.
Continuous cross-connection channels increase flexibility and save wiring effort
