The Siemens SENTRON 3VA9604-0JC43 is a TA4.3 circular conductor terminal — a wire connector designed to land four large-gauge cables (120–240 mm² each) on a single SENTRON MCCB, with an integrated tap-off point for control wiring.
The stripped-length window of 23.1–44.5 mm gives the installer room to land the conductor without trimming more than necessary; the longer end of that range suits the 500 kcmil bend radius.
This connector mounts directly to the line-side or load-side terminals of a SENTRON MCCB. It replaces the standard lug kit when you need to parallel four outgoing feeders or bring four incoming supply cables to one breaker. The control wire voltage tap-off allows picking up control power directly at the breaker terminals without a separate fused tap block.
