Wire connector, large, with and without control wire tap
The wire connector, large, 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, large is an external terminal, i.e. it projects beyond the external contour
of the breaker's termination area. This means that cables with a larger cross-section can be
connected.
The terminal cover extended plus the required assembly materials are supplied as standard
with all wire connectors, large. 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)).
