The SENTRON 3VA1110-1AA46-0AG0 is a 4-pole switch disconnector on the IEC frame 160, rated at 100 A, with clamp terminals. It carries no overload or short-circuit protection — it is a pure isolating and switching device, not a circuit breaker.
This is a panel-mounted disconnect for a 100 A branch circuit where you already have upstream overcurrent protection. The auxiliary and alarm contacts let the controls know whether the disconnect is open or closed and whether it has tripped — useful in a cement plant where a locked-out motor feeder means the kiln feed stops and you need that status in the DCS without walking the MCC floor.
