3VA molded case circuit breakers with UL and IEC certification
186 Manual, 01/2019, L1V30435333-01
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. Both variants are available in aluminum and
copper versions.
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
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 equipment (Page 203)).
The following tables show all the possible cable connections of the wire connector, 2 cables.
