Wire connector with and without control wire tap
The wire connector 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.
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 is an internal component, i.e. it is contained within the external contour of
the molded case circuit breaker. As a result, the size of cable cross section which can be
connected is limited by the geometry of the breaker's termination area.
The tables below show all the types and sizes of cable which can be connected to a wire
connector.
