Deployment context
The 3VA9154-0JC12: This connector mounts inside the 3VA1 plug-in base or withdrawable cradle — it is not a standalone terminal block. The 1.2 in strip length (30 mm) is the factory spec; stripping shorter risks insulation under the clamp, longer leaves bare conductor exposed past the pressure plate. Order four pieces per unit as the description notes.
Lifecycle status is active — this is a current-production SENTRON accessory, not a phase-out or NRND line. No official successor exists because the part has not been replaced.
