It accepts copper conductors from 4 AWG up to 350 kcmil, both stranded and finely stranded, which covers the full range of feeder and branch-circuit cable sizes you'd typically land on a 250 A frame breaker. Each terminal takes a stripped length of 0.8 in, so strip your cables to that mark before insertion — no guessing. The box-terminal design clamps the conductor with a screw, giving a gas-tight connection that holds up under thermal cycling in a warm panel. Rated for copper only; if your install uses aluminum, you'll need a different lug.","metaTitle":"SENTRON 3VM9253-0JA12 Box Terminal, 25–185 mm², 3VM 250","metaDescription":"SENTRON 3VM9253-0JA12 box terminal set for 3VM 250 breakers.
