The Siemens 3VA1340-1AA32-0DA0 is a 3-pole switch disconnector in the 3VA1 IEC frame 400 series, rated at 400 A continuous current (In). It is built for isolating a circuit under load — not for overload or short-circuit protection, so it needs upstream overcurrent devices. The integrated undervoltage release (208-230 V AC, 50/60 Hz) drops the switch open if control voltage falls, which is a standard safety interlock for motor feeders or conveyor drives where loss of control power should kill the load.
