It ships as a bag of 10 units, so one order code covers a full bank of starters in a typical panel. Mounting is pluggable on the BaseUnit. The 21 mm depth and 8 mm width keep the panel fill factor tight; at 47 mm tall it clears standard DIN-rail spacing. Rated for industrial vibration: 15 mm amplitude up to 6 Hz, then 2 g from 6 Hz to 500 Hz. Shock resistance is 6 g for 11 ms — that covers the mechanical stress of a contactor closing nearby or a forklift bumping the panel during commissioning. ## Environmental range and compliance Degree of pollution 2 means it's rated for normal industrial environments with only non-conductive contamination; no special sealing required inside a standard IP54 cabinet. The substance prohibitance date of 04/15/2016 aligns with RoHS and REACH compliance timelines — this cover meets the EU material restrictions in effect since that date.","metaTitle":"Siemens 3RK1908-1DA00-2BP0 Infeed Bus Cover, ET 200SP, Activ","metaDescription":"Siemens 3RK1908-1DA00-2BP0 infeed bus cover for ET 200SP motor starters.
