2.4.9 Isolated 3-phase busbar system
For 3RV1 frame sizes S00, S0, and S2, 3-phase busbars can be used to
quickly and easily provide line side feeding when mounting circuit breakers/
MSPs on to DIN rail. There is only one power supply, via a feed-in terminal.
The 3-phase busbar systems are safe from fingers and are shock protected
DIN VDE 0106 Teil 100. They are rated for the short-circuit stress that can
occur on the output side of the connected circuit breakers/MSPs.

Versions
The 3-phase busbars take 2 to 5 circuit breakers/MSPs, depending on the
model. There are busbars with more generous spacing for circuit breakers/
MSPs with accessories attached on the side
