Continuous current rating is temperature-dependent: 630 A at 40 °C, derating to 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C — critical for panel builders calculating fill factor and ventilation in sealed enclosures. Maximum power loss is 162 W, which drives internal heat rise and must be factored into the enclosure's thermal budget, especially when multiple breakers are ganged.","metaTitle":"Siemens 3VA2463-5HN32-0KC0 SENTRON MCCB, 630 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0KC0 molded case circuit breaker, 630 A continuous, 3-pole, 187 kA at 240 V.
