The 45 mm width matches the standard footprint of the S0 frame, so the adapter sits flush in the panel without wasting DIN rail space. Snap-on mounting lets you click it onto the rail without tools — useful when you're populating a row of breakers and want to keep assembly time down. ## Snap-on DIN rail, 23 mm depth, 26 mm height Depth is 23 mm, height is 26 mm. For a panel-builder planning gland-plate clearance or door swing, the shallow depth means the adapter plus breaker stays inside a 100 mm enclosure depth with room for wiring. The 45 mm width is the dimension that matters for fill factor on the rail — it takes one 45 mm slot per unit. Vibration resistance is tested at 2 m/s² from 5.8 to 500 Hz, with shock rated at 6 m/s² semi-sinusoidal. That's within the range for industrial control panels mounted on machine frames or conveyors — the adapter won't shake loose under normal plant floor conditions. Sourced through independent distribution against an RFQ.","metaTitle":"Siemens 3RA6890-0BA SIRIUS Adapter 45mm for 3RV1.2/3RV2.2","metaDescription":"Siemens 3RA6890-0BA SIRIUS adapter for Size S0 circuit breakers, 45mm width, 25A at 400V, snap-on DIN rail.
