Horizontally / vertically orientable rear terminal for main circuit connection
The rear connection with variable orientation permits connection of connection bars and cable
lugs to the rear of the guide frame. The rear main terminal is supplied mounted on the 󹪞ange of
the guide frame and can also be rotated subsequently by the user.
Copper/aluminum cable connection bar
A cable lug is required for connection.
The circular conductor terminal for cable lugs is mounted on the vertically oriented rear
terminals of the guide frame.
A total of up to four cables with a maximum cross-section of 240mm

can be connected to a
CuAl cable terminal.

Circular conductor terminals cannot be used for Cu/Al cables at rated currents greater than
1000A.
Extended front connection
The extended front connection for the withdrawable breaker is an alternative to the rear
connection. It enables the connections to be accessed from the front. It is mounted directly on
the guide frame and projects beyond the guide frame contour.
Front connection bars, broadened
The front connection bars, broadened permit front connection of broadened connection bars
and up to four cable lugs per phase and thus provide additional 󹪞exibility. They are screwed to
the extended front connections (not included in the scope of delivery) and protrude beyond the
guide frame contour.
Rear connection bars, broadened
The rear connection bars, broadened provide more space for connection of broadened busbars.
They are mounted on the horizontally oriented rear connections of the guide frame.
