Table 1-2: Mounting methods
Screw-on mounting
The SIRIUS switching devices can be screwed on to a flat surface.
Please note the following points with some of the devices:
• 3RV1 circuit breaker, frame sizes S00/S0: Push-in lugs are required for
screw-type mounting
• 3RP15 time relay: Push-in lugs are required for screw-type mounting
• Coupling links: No screw-type mounting
• Soft starters: No screw-type mounting
Snap-on mounting
The SIRIUS switching devices are snapped onto 35 mm rails in acc. with
DIN EN 50 022 without a tool.
The devices 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.
