Its breaking capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that govern its fault-interruption capability in low-voltage distribution panels. The 63 A rating holds flat from 40 °C through 50 °C; derating begins at 55 °C (60.48 A) and drops to 56.7 A at 70 °C. For a panel running warm — say a packed enclosure near the upper operating limit of 70 °C — the effective ampacity is about 10% below the nameplate, so the load circuit needs to stay under that derated figure. At 415 V the rating drops to 75.6 kA, and at 690 V to 11.9 kA — the voltage-dependent curve is typical for an air-break design, and the 690 V figure is the one to check if the breaker lands on a 690 V line side. ## Deployment context This MCCB is sized for DIN-rail or panel-mount installation in a low-voltage switchboard or distribution board. The 101.6 mm width (4-pole) and 70 mm depth fit standard SENTRON 3VA cutouts; verify the back-panel clearance for the 130 mm height plus arc-chamber venting.","metaTitle":"Siemens 3VA1063-4ED42-0AD0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1063-4ED42-0AD0 SENTRON molded case circuit breaker. 63 A rated current, 4-pole, breaking capacity 121 kA at 240 V.
