This cover snaps onto the device to prevent accidental contact with live ring-lug terminals after wiring — a straightforward panel-safety add-on for a motor starter protector that already has its auxiliary switch wired. Listed lifecycle stage is current, meaning Siemens still produces and supports this cover as an active catalog item. The Substance Prohibitance date of 05/01/2012 aligns with RoHS compliance — the cover meets the EU RoHS directive effective from that date. ## Integration note Designed for 3RV20 size S00 and S0 devices — the two smallest frame sizes in the SIRIUS motor starter protector range. The ring terminal lug connection on the transverse auxiliary switch means the wire terminates with a ring lug under a screw; the cover then fits over that terminated connection, so verify the lug diameter clears the cover's interior before final assembly.","metaTitle":"Siemens 3RV2908-4AA10 SIRIUS Touch Protection Cover","metaDescription":"Siemens SIRIUS 3RV2908-4AA10 touch protection cover for transverse auxiliary switches with ring cable lug connection, for 3RV20 size S00, S0.
