Wire connector, 2 cables, with and without control wire tap
The wire connector, 2 cables, is available under separate article numbers depending on
whether it is ordered with or without a control wire tap. With the exception of the hole for the
control wire tap, both wire connectors are technically identical, i.e. the same cable cross
sections can be connected to both variants.
Note
All control wire taps offered in the 3VA molded case circuit breaker portfolio are permitted
only up to a maximum current of 15 A.
Suitable cable cross-sections: Cables up to a maximum of 2.5 mm
2
can be connected.
The wire connector, 2 cables is an external terminal, i.e. it projects beyond the external
contour of the breaker's termination area. The 2-cable capacity of the terminal allows cables
with large cross-sectional area to be connected.
The extended terminal cover plus the required assembly materials are supplied as standard
with all wire connectors, 2 cables. This is used for insulation and provides degree of
protection IP4x at the front of the molded case circuit breaker and degree of protection IP2x
at the infeed side and load side (see chapter Insulating measures (Page 246)).
