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.","metaTitle":"Siemens 3VA1340-1AA32-0DA0 Switch Disconnector, 400A, 3-Pole","metaDescription":"Siemens 3VA1340-1AA32-0DA0 switch disconnector, 400A rated, 3-pole, with undervoltage release 208-230 V AC.
