Breaking capacity reaches 75.6 kA at 240 V, stepping down to 52.5 kA at 415 V and 11.9 kA at 690 V, which covers most industrial distribution panels and motor control center infeeds. At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard Siemens 3VA1 mounting footprints. The 3-pole block occupies three adjacent slots in a distribution panel or motor control center bucket.","metaTitle":"Siemens 3VA1163-3EF32-0AA0 SENTRON MCCB, 63 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1163-3EF32-0AA0 molded case circuit breaker, 3-pole, 63 A rated at 40 °C, 75.6 kA breaking at 240 V.
