Interrupting rating drops as line voltage climbs: 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V or 690 V. That means the same breaker covers 400 V class panels but needs coordination review if the system runs at 480 V or higher. Thermal rating holds flat at 63 A from 40 °C up to 50 °C, then derates gradually to 58 A at 70 °C. No need to oversize for a warm enclosure unless ambient pushes past 50 °C. ## Dimensional fit and panel integration Measures 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON 3VA switchboard or distribution panel cutouts without re-drilling. Depth is tight for shallow enclosures; confirm 70 mm clearance behind the door.","metaTitle":"Siemens 3VA1163-3EF36-0AE0 SENTRON MCCB, 63A, 75.6kA @240V","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0AE0 molded case circuit breaker, 63A rated at 40°C, 3-pole, 75.6kA breaking capacity at 240V AC.
