Mounting position
You can install the 3RV1 circuit breakers anywhere.
Snap-on mounting
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
Screw-on mounting
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.
