Front bus connectors offset
Front bus connectors offset can be installed to connect very large busbars and compression
lugs outside the termination area of a 3VA molded case circuit breaker. Front bus connectors
offset increase the distance between pole centers of the terminals of the molded case circuit
breaker.
Distance between pole centers with front bus connectors offset:
● 3VA10 / 3VA11: 35 mm
● 3VA12 / 3VA20 / 3VA21 / 3VA22: 45 mm
● 3VA13 / 3VA14 / 3VA23 / 3VA24: 70 mm
All front bus connectors offset 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).
