At 690 V it holds 4.5 kA, so this is a low-voltage main or feeder breaker, not a motor-circuit device. Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. Physical footprint is 105 mm wide, 181 mm tall, 86 mm deep — standard SENTRON 3VA frame size for 250 A. Fits the same panel cutout and busbar spacing as other 3VA2 breakers in this current class.
Internal accessories — what ships inside the frame
The UVR drops the breaker on loss of control voltage — standard for safety disconnects on conveyor or press feeds where a voltage dip must open the main. The base switch mechanism is order code 3VA2225-6HN32-0AA0. That's the heat the breaker dumps into the enclosure — factor it into your panel thermal calculation, especially if the cabinet is sealed or stacked with multiple breakers. The storage limit governs shipping and warehousing, not running conditions.
Lifecycle and sourcing — active, quoted to order
If you need ground-fault detection, this is not the right suffix.
