It provides visible isolation of a circuit under load — a safety disconnect, not a protective device. It ships without overload or short-circuit protection elements, so it relies on upstream fusing or a breaker for fault clearing. ## Where it lands in a panel The 3-pole design suits three-phase loads like a motor feeder or main incomer where you need a lockable disconnect point. The 400 A continuous rating is the thermal current — it handles that load in free air without derating. Because there is no integral overcurrent release, the switch disconnector relies on the upstream protective device for fault interruption. The undervoltage release (24 V DC) is an accessory that trips the switch on loss of control voltage, typical for safety circuits or emergency-stop chains.","metaTitle":"Siemens SENTRON 3VA1340-1AA32-0BA0 Switch Disconnector, 400A","metaDescription":"Siemens SENTRON 3VA1340-1AA32-0BA0 switch disconnector, 400A, 3-pole, IEC frame 400.
