It is the disconnect-only variant in the 3VA molded-case family, designed for applications where the upstream feeder already provides protection and you need a load-break switch with a clear open position for lockout/tagout. Above that it steps down: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. The main circuit connection is a front-terminal busbar connection, and the device accepts an optional motor drive for remote switching. IP40 protection on the front face suits enclosed panel mounting. The 15 000-cycle typical mechanical service life reflects a switch disconnector duty cycle — no arc-chamber wear from fault interruption.","metaTitle":"Siemens 3VA1225-1AA32-0AA0 Switch Disconnector, 250 A","metaDescription":"Siemens 3VA1225-1AA32-0AA0 SENTRON switch disconnector, 250 A at 690 V AC, 3-pole, MCCB design.
