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. Both variants are available in aluminum and copper versions.
Note
A maximum current limit of 15 A applies to all control wire taps for 3VA UL molded case
circuit breakers. Control wire overcurrent protection must be applied separately.
Suitable cable cross-sections: Cables up to maximum AWG 12 / 2.5 mm

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.
