Circular conductor terminal with and without auxiliary conductor terminal
The circular conductor terminal 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 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 circular
conductor terminal.
