The headline breaking capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 17 kA at 690 V — so the SCCR you need for a 480 V distribution board is comfortably covered, and the 690 V figure still handles most motor-circuit fault levels. The ETU850 electronic trip unit handles the protection curve; a shunt trip (STL) is integrated for remote opening. ## Thermal derating — the real-world current you can count on At 45 °C it's 600 A; at 50 °C, 570 A; at 55 °C, 540 A; at 60 °C, 510 A; at 65 °C, 480 A; and at 70 °C, 450 A. If your panel internal ambient runs hot — say 50 °C in a sealed enclosure — this breaker still delivers 570 A continuous, which is the figure to use for your load schedule, not the 40 °C number. ## Operating environment and approvals The ETU850 release is electronic, so no phase-failure detection is built in; if you need that, it's handled upstream or by the protection relay.","metaTitle":"Siemens 3VA2463-5KP32-0HL0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0HL0 molded case circuit breaker, 630 A rated, 187 kA breaking at 240 V.
