Above that, the breaker derates linearly: 618 A at 55 °C, 607 A at 60 °C, 595 A at 65 °C, and 583 A at 70 °C. That 583 A at 70 °C figure is the hard ceiling; the breaker will nuisance-trip above that continuous load. Size your feeder conductors and upstream protection accordingly. The breaker measures 184 mm wide, 248 mm tall, and 110 mm deep. Four-pole at 184 mm means each pole takes about 46 mm of DIN-rail width — standard for this class. Maximum power loss is 195.4 W — that heat has to leave the enclosure; factor it into your thermal calculation.","metaTitle":"Siemens 3VA1463-5GF42-0DA0 SENTRON MCCB, 630 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1463-5GF42-0DA0 molded case circuit breaker, 630 A, 4-pole, TM240 trip unit, 187 kA at 240 V.
