At 415 V and 440 V it still holds 242 kA, and at 690 V it drops to 9 kA, which is the standard derate for this class of breaker above 600 V. The IP40 front protection keeps dust and tools out of the mechanism in a clean panel environment. At 55 °C it derates to 477 A, at 60 °C to 455 A, at 65 °C to 432 A, and at 70 °C to 410 A. It mounts into a standard SENTRON 3VA panel footprint with bolted bus connections. The 3-pole form factor matches existing 3VA-series switchboard and distribution panel cutouts.","metaTitle":"3VA2450-7KQ32-0AA0 SENTRON MCCB, 500 A, 3-Pole, ETU860","metaDescription":"Siemens SENTRON 3VA2450-7KQ32-0AA0 molded case circuit breaker, 500 A at 40 °C, 3-pole, ETU860 electronic trip unit, 330 kA at 240 V.
