On busbar system
All device combinations can be mounted on a 60 mm busbar system. Busbar adapters have
to be used for busbar mounting. One adapter is required for direct-on-line starters; a pair of
adapters is required for reversing contactor assemblies.

busbar
The busbar adapters and the associated mounting parts can be purchased as accessories.
Component parts of the different mounting variants can be determined via our Online
Configurator (Page 27).
Adapter types for busbars
Busbar adapters and device holders: Busbar adapters are available with or without pre-
assembled connecting cables. Busbar adapters without connecting cables are known as
"device holders".
Busbar adapters and device holders
are available in the adapter lengths 200 mm and
260 mm. All device combinations can be mounted on the long adapter.
Size S2 is distinguished by width and by the number of pre-mounted DIN rails.
