2 3RV1 circuit breakers
To enable the circuit breakers to be mounted without using up too much
space, and to ensure that the infeed is economical in terms of both time and
money, the switches are mounted directly onto busbar systems using bus-
bar adapters.
The circuit breakers are snapped onto the adapter and connected at the
input side. This prepared unit is mounted directly onto the busbar systems,
thus both attaching it mechanically and establishing electrical contact.
The adapters are suitable for the following systems:
Busbar systems with
center-to-center spacing
40 mm systems
60 mm systems

Table 2-14: Busbar systems

The following accessories are available for busbar adapters:
• Modules that can be mounted on either side to widen the adapters
• Busbar holder for 3 rails
• Molded-plastic covers for 3 terminals (40 mm system)
• Molded-plastic cover profiles for shock protection
The following table lists the dimensions of the busbar adapters and accesso-
