The interrupting ratings tell the story: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. At 55 °C it derates to 243 A, at 60 °C to 237 A, and at 65 °C to 230 A — hitting 223 A at 70 °C. The 140 mm width for a 4-pole frame is standard for this class — verify the mounting footprint matches the existing backpanel drilling if replacing an older frame. ## What the undervoltage release means for the circuit That's standard for applications where you want automatic disconnection on brownout or loss of control power (safety circuits, emergency-stop chains, or sequencing interlocks). The UVR is factory-fitted, not a field-add accessory, so verify the control voltage matches your panel's auxiliary supply before wiring.","metaTitle":"SENTRON 3VA1225-6GF42-0DA0 MCCB, 250 A, 4-Pole, 220 kA at 24","metaDescription":"SENTRON 3VA1225-6GF42-0DA0 molded case circuit breaker, 250 A, 4-pole, TM240 release. 220 kA at 240 V, 154 kA at 415 V.
