3VA molded case circuit breakers with UL and IEC certification

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.
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, 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 extended terminal cover 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 equipment (Page 203)).
The table below shows all the types and sizes of cable which can be connected to a wire
connector, large.
