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.","metaTitle":"Siemens 3VA9154-0JC12 SENTRON Wire Connector, 4 AWG–350 kcmi","metaDescription":"Siemens SENTRON TA2.1 wire connector for 3VA1 plug-in/withdrawable units.
