Distribution
General
For connections, the distribution block uses a proven technique, i.e. spring terminals.
Downstream circuits are connected from the front, without screws, to spring
terminals. Contact pressure does not depend on the operator. It automatically adapts
to the size of the conductor (minimum size = 1mm²). Contacts are insensitive to
v brations and thermal variations.
Only one cable (flexible or rigid, without a metal ferrule) can be inserted in a spring
terminal.
Degree of protection: IPxxB.
Advantages
a reliable electrical connection, no maintenance required (tightness guaranteed
over time)
the fast connections make phase balancing very easy.
rewiring is very easy if the switchboard is expanded or modified.

Application
Distribution over half or full rows of modular devices. It is generally supplied by a
device at the head of a group of outgoers (NG125, INS, C60, etc.).

Electrical characteristics
rated insulation level Ui = 500 V
impulse withstand voltage Uimp = 6 kV
short-circuit withstand current: the reinforced breaking capacity due to cascading
in circuit-breaker combinations is maintained. The worst-case situations have been
tested.
63/80 AMulticlip distribution blocks:
4 mm² cable outgoer: Imax = 32 A
6 mm² cable outgoer: Imax = 40 A
two 6 mm² cables: Imax = 63 A.
Supply
Via tunnel terminals up to 25 mm², generally from a device supplying a group of
outgoers.
The tunnel terminals are positioned to facilitate cable entry and screw tightening.
They are designed for cables arriving from the top or bottom.
Distribution
for the full-row Multiclip, 4P (04004), each phase offers:
2 connection points for 6 mm² max. cable
7 connection points for 4 mm² max. cable
the neutral offers:
4 connection points for 6 mm² max. cable
13 connection points for 4mm² max. cable
for the half-row Multiclip, 4P (04008),
each phase offers:
2 connection points for 6 mm² max. cable
2 connection points for 4 mm² max. cable
the neutral offers:
4 connection points for 6 mm² max. cable
4 connection points for 4 mm² max. cable
Each connection point can receive a single cable, either flexible or rigid.
Installation
clipped onto the rear of modular rail
screwed to plain or slotted backplate
