It ships as a pack of three units for use with 3VA55, 3VA65, and 3VA66 frames. This is a lug-style connector, not a control-wire tap — there is no provision for a control wire tap on this terminal. It handles stranded copper or aluminum cable from 500 kcmil minimum up to 750 kcmil maximum, and finely stranded copper in the same range. Strip length is 1.1/1.7/2.3 inches. Torque is 42.4 Nm for stranded (240-300 mm²) and finely stranded (240-240 mm²) copper. ## Installation context This terminal mounts externally on the breaker — it is not a DIN-rail accessory. It adds three cable connection points to the line or load side of the 3VA55/3VA65/3VA66 frame. The 42.4 Nm torque is high; a torque wrench or hydraulic crimper is expected for field termination.","metaTitle":"Siemens SENTRON 3VA9673-0JJ34 Wire Connector, 500-750 kcmil,","metaDescription":"Siemens SENTRON TA4.2 wire connector for 3VA55/3VA65/3VA66.
