3VA molded case circuit breakers with IEC certificate

Front bus connectors extended
Bus connectors extended can be installed to connect larger busbars and compression lugs
outside the termination area of a 3VA molded case circuit breaker. The front bus connectors
therefore extend the terminal of the breaker.
All front bus connectors extended are supplied as standard with phase barriers to provide
insulation between individual phases. For further information, please refer to chapter
Insulating measures (Page 246).
An auxiliary connection can be implemented using a special control wire tap. For further
information, please refer to chapter Auxiliary conductor terminal (Page 269).
