Above that, derating is gradual: 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. The front face carries an IP40 protection class — suitable for dry indoor panels where no water spray is expected. No undervoltage release, no shunt trip, no ground-fault monitoring, and no N-conductor protection are fitted on this variant.","metaTitle":"Siemens 3VA1063-4ED42-0AC0 SENTRON MCCB, 63 A, 4-Pole, 70 mm","metaDescription":"Siemens SENTRON 3VA1063-4ED42-0AC0 molded case circuit breaker, 63 A rated continuous current at 40 °C, 4-pole, breaking capacity 121 kA at 240 V.
