Product details

The 3VA9773-0JJ34: The TA 6.1 designation means the connector body has a specific barrel and set-screw geometry matched to the 3VA57/3VA67 bus bar stabs. It is not a generic lug — it bolts directly to the breaker's line-side pads without an adapter plate.

The 3VA9773-0JJ34 carries an active lifecycle status from Siemens. It is a current-production accessory for the SENTRON 3VA molded-case breaker family.

These connectors install on the breaker's line terminals inside the enclosure. No DIN-rail mounting — they are part of the breaker assembly itself. The 1.0-3.0 inch strip length range means the installer must gauge the insertion depth per hole; the longest strip is for the outermost hole where the conductor must reach past the adjacent terminal.
