The 7 000 A maximum and 750 A minimum trip settings give the ETU850 wide adjustment range for coordination studies. The breaker holds its full 500 A rating through 50 °C ambient. Above that, it derates to 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, and 410 A at 70 °C. Maximum power loss is 99 W — account for that heat in the panel's thermal budget, especially in a sealed enclosure. The 3-pole form factor is standard for 500 A MCCBs; verify the busbar spacing and lug kit compatibility with your existing panel layout. Communication function is onboard, so it can report status and trip data to a higher-level system without an external module.","metaTitle":"Siemens 3VA2450-6KP32-0AA0 SENTRON MCCB, 500 A, 242 kA at 24","metaDescription":"Siemens 3VA2450-6KP32-0AA0 SENTRON molded case circuit breaker, 500 A continuous, 242 kA breaking at 240 V.
