The 40 mm width and 100 mm depth keep the footprint tight against the DIN rail, leaving room for additional components in a crowded enclosure. Operating temperature spans -20 to +60 °C, with storage and transport tolerance down to -55 °C and up to +80 °C. The 63 A rating at 400 V AC is the operational current the connector handles continuously through the infeed bus. For a motor starter lineup, this sets the ceiling for how many downstream starters can be fed before the bus needs splitting or a higher-rated infeed. Pollution degree 3 (industrial environment with conductive dust or condensation) is baked into the design, so the connector tolerates the grime inside a typical panel without creepage failures. Vibration resistance is specified at 2 m/s² from 5.8 to 500 Hz with 15 mm displacement at lower frequencies — ten cycles per axis. Shock resistance is semi-sinusoidal 6 m/s² at 10 ms in all three axes, positive and negative. These numbers matter for applications mounted on machinery or near conveyors where the panel sees continuous vibration. Installation altitude is limited to 2,000 m above sea level without derating. Above that, the air density drop reduces the dielectric withstand and cooling — typical for any industrial control gear, but worth flagging if the panel sits in a high-altitude plant. ## Active production — sourcing posture The 3RA6890-1AA carries an active lifecycle status from Siemens.","metaTitle":"Siemens 3RA6890-1AA SIRIUS Expansion Connector, 63A","metaDescription":"Siemens 3RA6890-1AA SIRIUS expansion connector for 3RV19/3RV29 infeed systems. 63A at 400V AC, plug-in fixing, 40x55x100mm.
