That means for a panel running at typical ambient (40–50 °C), you get full 500 A capacity; push past 55 °C and the thermal curve governs the real ampacity. The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Communication function is built in, so it can talk to a higher-level system for metering and event logging — useful for a power-monitoring scheme without an add-on module. Dimensions: 248 mm height, 138 mm width, 110 mm depth. Power loss is 99 W maximum at rated current — that's the heat to dissipate in the enclosure. For a panel with multiple breakers, factor that into the thermal budget; a 500 A frame pulling 99 W is typical for an electronic-trip unit at this ampacity.","metaTitle":"Siemens 3VA2450-6KQ32-0AA0 SENTRON MCCB, 500 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2450-6KQ32-0AA0 molded case circuit breaker, 500 A continuous, 242 kA at 240 V, ETU860 release, ground-fault monitoring.
