Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, giving solid fault-clearing headroom for industrial service entrances or sub-distribution boards. The 75.6 kA at 240 V is the high-fault rating for 277/480 V wye systems where the line-to-neutral fault can be severe. At 415 V (common in 400 V three-phase networks) it's still 52.5 kA, and at 440 V it drops to 32 kA. At 500 V and 690 V it holds at 11.9 kA — that's the ceiling for the 690 V class. Thermal derating is mild: 63 A holds from 40 °C through 50 °C, then drops one amp per 5 °C step to 58 A at 70 °C. If your panel ambient runs 55 °C, you still get 62 A — no need to oversize for a warm cabinet. ## Mounting and Integration — Panel Fit The 3VA1163-3EE46-0AA0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep. The 4-pole footprint matches the usual 4-module width for three-phase plus neutral switching.","metaTitle":"Siemens 3VA1163-3EE46-0AA0 SENTRON MCCB, 63A, 4-Pole, 75.6kA","metaDescription":"Siemens SENTRON 3VA1163-3EE46-0AA0 molded case circuit breaker, 63A at 40°C, 4-pole, TM220 release, 75.6kA breaking at 240V.
