That's useful when you're paralleling conductors to meet ampacity requirements on a 1000 A frame, or when you need to tap multiple downstream loads off a single breaker lug. This terminal bolts directly onto the line-side or load-side pads of the 3VA15 or 3VA25 breaker frame. No DIN-rail mount — it's a lug, not a module. The circular conductor terminal design (TA4.3) uses a compression-style barrel that accepts both copper and aluminum conductors (stranded or finely stranded), so you don't need separate bi-metallic adapters for aluminum feeders. The control wire tap is not included — this is a straight power terminal, not a combination lug with a spade for control wiring.","metaTitle":"SENTRON 3VA9603-0JJ43 TA4.3 Wire Connector, 4/0-500 kcmil","metaDescription":"SENTRON 3VA9603-0JJ43 TA4.3 circular conductor terminal for 4 cables 120-240 mm².
