2 3RV1 circuit breaker
You can install the 3RV1 circuit breakers anywhere.
The circuit breakers are mounted by snapping them onto 35 mm rails that
comply with DIN EN 50 022. The circuit breakers with a frame size of S3
require a rail with an installation height of 15 mm. Alternatively, they can also
be snapped onto 75 mm rails.

Figure 2-31: Mounting the circuit breakers onto the rail

The circuit breakers are attached to a flat surface with 2 screws. For circuit
breakers in frame sizes S00 and S0, two push-in lugs (3RB1900-0B) (pack of
10) are also required.
Circuit breakers in frame sizes S2 and S3 can be screwed directly onto a
base plate.
