Installation terminal blocks

The preferred choice for

building industry

The installation terminal blocks are largely used in distribution
cabinets of public buildings and meet wiring and connection
requirements of installations designed in accordance with
DIN VDE 0100 or DIN VDE 0108.

They allow:
Compact signal distribution thanks to multi-level terminal
locks
Insulation test without disconnecting the neutral conduc-
tor thanks to neutral disconnect function on TNS or TNC-S
networks.

Select from our various choice of functions and technologies

Installation terminal blocks
Our product family offer multi-circuit confguration to ease the
10 distribution of single phase or 3 phase circuits.
Installation terminal blocks are proposed in screw clamp and
spring clamp technologies.
Various confgurations allow distribution of feed-through, neutral,
neutral disconnect and ground circuits in a compact format.
Select from our single type terminal blocks or prefer multi-circuit
compact and closed solution (screw clamp technology) combin-
ing up to 9 circuits on one single terminal block.
Neutral bar is aligned with standard single deck terminal blocks
and ensures full compatibility with standard feed-through, neutral
disconnect, or ground terminal blocks.

Neutral disconnect terminal blocks
Neutral disconnect function is mandatory on TNS or TN-C-S
networks used in public buildings and installation complying with Multi-level screw clamp terminal Multi-level spring clamp terminal
VDE 0108. blocks blocks
Standard specifes:
"The distribution must be designed so that it is possible to measure
the insulation resistance of all conductors to ground for each indi-
vidual outgoing circuit with conductor cross sections up to 10 mm².
This measurement must be performed without disconnecting the
neutral conductor. e.g. through the installation of neutral conductor
disconnect terminal blocks."
Our terminals allow simple connection or disconnection of neutral
bar thanks to a sliding link and are available in 2 technologies 1SNC161166S0201
