If your system fault current exceeds these at the point of installation, you need a current-limiting device ahead of it or a higher-rated frame. Above that it starts to derate: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C. Dimensions: 158 mm height, 140 mm width, 70 mm depth. Verify the UVR coil voltage against your control circuit before wiring.","metaTitle":"Siemens 3VA1225-6EF42-0DC0 SENTRON MCCB, 250 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1225-6EF42-0DC0 molded case circuit breaker, 250 A continuous, 4-pole, TM240 release.
