The interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V, which gives the site electrical engineer real selectivity headroom on a 415 V distribution board. The thermal derating curve is flat to 50 °C (63 A), then drops to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. In a warm panel enclosure, the commissioning engineer sizes the load at the 55 °C or 60 °C figure, not the 40 °C nameplate. Front-face protection is IP40, so it is suitable for dry indoor enclosures but not washdown zones. The design of short-circuit protection for DC networks is covered in the 3VA molded case circuit breaker device manual — reference the manual for DC applications.","metaTitle":"Siemens 3VA1063-3ED42-0JA0 SENTRON MCCB, 63 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1063-3ED42-0JA0 molded case circuit breaker, 63 A, 4-pole, line protection, 75.6 kA at 240 V.
