Above 50 °C the breaker derates linearly: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. If the panel ambient runs at 60 °C, the continuous load must stay under 58.275 A — the 63 A nameplate applies only up to 50 °C. No auxiliary contact is fitted as standard; the shunt trip (STL) is the only integrated auxiliary release.","metaTitle":"Siemens 3VA2063-5HN32-0KA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5HN32-0KA0 molded case circuit breaker, 3-pole, 63 A, ETU350 release, interrupting capacity 187 kA at 240 V.
