Circular conductor terminal, large, with and without auxiliary conductor terminal
The circular conductor terminal, large, is available under separate article numbers depending
on whether it is ordered with or without an auxiliary conductor terminal. With the exception of
the bore for the auxiliary conductor terminal, both circular conductor terminals are technically
identical, i.e. the same cable cross sections can be connected to both variants.
Note
All auxiliary conductor terminals included in the 3VA molded case circuit breaker portfolio
have a maximum current-carrying capacity of 6 A.
Suitable cable cross-sections: Cables with a maximum cross-section up to 2.5 mm
connected.
The circular conductor terminal 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 circular conductor terminals, large. This isolates the termination area, providing
degree of protection IP4x at the front of the molded case circuit breaker and degree of
protection IP2x at the infeed and load ends (see chapter Insulating equipment (Page 191)).
The table below shows all the types and sizes of cable which can be connected to a circular
conductor terminal large.
Circular conductor terminals large with or without auxiliary conductor terminal can be ordered
