This is a pure disconnector — no overload or short-circuit protection (no trip unit, no undervoltage release, no auxiliary contacts). Mechanical service life is 15 000 operating cycles typical. Mounts in a standard panel cutout for 3-pole MCCB-form disconnectors.","metaTitle":"Siemens 3VA1340-1AA32-0AA0 SENTRON Switch Disconnector, 400","metaDescription":"Siemens SENTRON 3VA1340-1AA32-0AA0 switch disconnector, 3-pole, 400 A rated current, 690 V AC, IP40 front.
