The standard valid for modular
terminals for connecting round copper
conductors with cross-section
between 0.2 0.12 1282250000 2012/2013
.
• Terminals that directly contact
the conductor through cutting
or which create contact points
by penetrating the insulation, for
example insulation eg.2 mm2
and 300 mm2
(AWG 24/600 kcmil), for electric
circuits 1000 AC/1000 or
up 1500 DC.0
- 6.75 1.
This standard can used a
guide for:
• Terminals that require the
attachment special fixtures the
conductor such tab wire-wrap
connectors, etc.
In conjunction with this and having an
overriding importance:

controlgear
–General stipulations
(IEC 60947-7-1)
(EN 60947-7-1)
This standard defines requirements
for feed-through and disconnect-test
terminals with screw screwless
terminal points which are primarily
intended for industrial applications or
similar and are attached carrier to
produce electrical and mechanical
connection between copper cables.0 -

Feed-through terminal
An insulating part consisting one or
more terminal groups that are isolated
from each other, and designed be
mounted carrier. The conductors may
be solid, multi-strand fine-strand
components, necessary with the
ends the conductors prepared for the
connection.
The rated cross-section selected from
the following standard cross-sections:
0.
Rated cross-section
The rated cross-section modular
terminal the size specified by
the manufacturer the conductor
cross-section that can connected to
the terminal, which certain thermal,
mechanical and electrical requirements
are based, and which intrinsic the
marking the terminal.
Verification the rated cross-section is
carried out with gauge, according to
IEC 60947-1.5 2.
The modular terminals possess a
rated connection capacity that at
least two steps smaller than the rated
cross-section. such
