The interrupting ratings span 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — figures that govern its fault-clearing capability at the system voltage present. The 63 A rating holds up to 50 °C ambient; above that, the continuous current derates 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. For panel builders, this means the breaker can be applied at its full nameplate in most ventilated enclosures, but a high-ambient compartment (e.g., adjacent to a drive or transformer) requires a downward adjustment. ## Auxiliary contacts and trip indication The trip indicator is present on the front face, aiding field-service techs during fault isolation. The 3VA1063-3ED42-0AH0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 70 mm depth is a key dimension for gland-plate clearance and shallow enclosure fit. Front protection class is IP40, suitable for general-purpose indoor panels. The 4-pole width (101.6 mm) matches the standard 100 mm grid for DIN-rail or mounting-plate layouts; verify busbar and lug spacing against the existing panel cutout.","metaTitle":"Siemens 3VA1063-3ED42-0AH0 SENTRON MCCB, 63 A, 4-Pole, 75.6","metaDescription":"Siemens 3VA1063-3ED42-0AH0 SENTRON molded case circuit breaker, 63 A rated, 4-pole, 75.6 kA at 240 V.
