It handles two cables per unit, copper or aluminum, stranded or finely stranded, from 400 kcmil up to 750 kcmil. Each set ships three units, enough to cover a three-phase panel. The built-in control wire tap (voltage tap-off) means you can pull a smaller-gauge sense or control wire directly from the main conductor — no separate fuse block or splice required. That saves a DIN rail position and a wiring step in the panel. ## Torque and strip length — what they mean on the bench For stranded cable in the 240–300 mm² range (roughly 500–600 kcmil), the terminal torque spec is 42.4 Nm. That's a firm pull on a long-handled torque wrench — not a screwdriver job. The stripped length is 1.1 in (about 28 mm), which tells your wireman how much insulation to remove for full contact in the compression saddle.","metaTitle":"Siemens 3VA9673-0JC24 SENTRON TA4.1 Voltage Tap, 2x400-750 k","metaDescription":"Siemens SENTRON 3VA9673-0JC24 TA4.1 circular conductor voltage tap for 2 cables, 400-750 kcmil.
