Each pack ships three units, each terminating up to four cables. Stranded copper or aluminum cable from 4/0 AWG up to 600 kcmil is torqued to 42.4 Nm on the main conductor pad; finely stranded copper (120–185 mm²) also lands at the same torque. Stripped length is 0.9 to 1.75 inches. ## What the torque spec means on the panel floor 42.4 Nm (roughly 375 in-lb) is a high-torque termination — expect to use a torque wrench with a hex socket, not a standard screwdriver. That clamping force is what keeps 600 kcmil terminations stable under fault-current thermal cycling. The terminal accepts four cables, so it's sized for paralleled feeds or multiple downstream loads in a single breaker lug well.","metaTitle":"Siemens 3VA9673-0JJ44 SENTRON TA4.4 Wire Connector, 4/0-600","metaDescription":"Siemens SENTRON TA4.4 wire connector for 3VA55/3VA65/3VA66 breakers.
