Per the datasheet, this unit is specified without overload protection and without short-circuit protection — it functions purely as a load-break disconnect for isolation and switching duty, not as a protective device. The 250 A continuous rating means this disconnect can carry full load current in a panel feeder or machine supply circuit without derating under normal ambient conditions up to 70 °C. Because there is no integral trip unit, upstream overcurrent protection must be coordinated separately — this is a disconnect-only device. Main circuit connections are busbar-type, front-terminal arrangement — this matches standard MCCB panel footprints and busbar systems for 250 A frame sizes. The unit includes a nut keeper kit per the description, which simplifies busbar mounting in the panel.","metaTitle":"Siemens 3VA1225-1AA32-0AF0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0AF0 switch disconnector, 250 A rated continuous current, 3-pole, 690 V AC / 500 V DC.
