It is built to IEC 81346-2 (reference code Q) and carries a 690 V AC / 600 V DC insulation voltage of 800 V. The front face is IP40, so it's splash-protected against tools and fingers but not washdown — suitable for dry indoor panel environments. It's designed for isolation and safe disconnection under load, not for circuit protection. The 15 000 mechanical operating cycles typical service life reflects a robust mechanism for frequent switching in a panel. The disconnector measures 70 mm deep, 140 mm wide, and 158 mm high. Main circuit connections are busbar-type on the front terminals. The design accepts up to 4 auxiliary switches (HQ type) and an optional motor drive.","metaTitle":"Siemens 3VA1225-1AA42-0AE0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA42-0AE0 switch disconnector, 250 A, 4-pole, 690 V AC, 600 V DC, IP40 front, 70 mm depth.
