It mechanically prevents the unit from being inserted or withdrawn when the main contacts are closed, enforcing a safe sequence for panel maintenance and swap-out without a full de-energization. ## Integration note This rear interlock mounts to the 3VA1 or 3VA2 molded-case switch frame. It does not alter the panel cutout or DIN-rail footprint — the interlock rod engages the operating mechanism through the existing escutcheon opening. Verify the rod length matches the enclosure depth before committing the BOM line.","metaTitle":"Siemens 3VA9088-0VM30 SENTRON Rear Interlock, for 3VA1/2 up","metaDescription":"Siemens SENTRON 3VA9088-0VM30 rear interlock accessory for 3VA1/2 plug-in and draw-out units up to 630 A.
