That makes it a pure disconnect for maintenance lockout or as a main switch ahead of downstream protection devices. The 250 A rating holds flat from 40 °C through 50 °C, then derates to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C — useful to know if the switch sits in a warm enclosure or near other heat sources. Front terminals accept busbar connection for the main current circuit. The 70 mm depth, 105 mm width, and 158 mm height fit standard MCCB panel cutouts and busbar layouts. The design accepts an optional motor drive for remote switching, and there is no undervoltage release fitted — that is a separate order if you need UVR protection.","metaTitle":"Siemens 3VA1225-1AA32-0AC0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0AC0 switch disconnector, 250 A rated at 40 °C, 3-pole, MCCB design, 690 V AC / 500 V DC, IP40 front.
