4.9.12 8US busbar adapter
4.9.12.1 Description
8US 3-phase busbar adapter
To save space when installing the motor starter protectors and to save time and money
when implementing the infeed, busbar adapters are used to attach the motor starter
protectors directly to busbar systems with center-to-center clearance of 60 mm.
The busbar adapters for busbar systems with a center-to-center clearance of 60 mm are
suitable for copper busbars in widths of 12 mm through 30 mm. The busbars can be 5 mm or
10 mm thick.
The motor starter protectors snap onto the adapter and are connected at the input side. This
ready-to-use unit plugs directly onto the busbar systems, thereby taking care of mechanical
fastening and electrical connection at the same time.
