Above that, it drops to 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. The maximum power loss is 192.9 W — a figure to check against enclosure ventilation, especially when ganging multiple breakers in a compact panel. Front protection is IP40, so it's suited for a dry indoor enclosure but not washdown areas.","metaTitle":"Siemens 3VA1463-5EF42-0AA0 SENTRON MCCB, 630 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1463-5EF42-0AA0 molded case circuit breaker, 630 A at 40 °C, 4-pole, TM240 thermal-magnetic trip, 187 kA at 240 V.
