Breaking capacity is 440 kA at 415 V AC and 187 kA at 690 V AC — enough headroom for high-fault installations like industrial substations or large motor control centers where selective coordination is required. The 3-pole design fits standard DIN-rail or panel-mount footprints. Rated current holds flat at 63 A across the full ambient range from 40 °C to 70 °C, so no derating is needed in a warm enclosure. ## Dimensions & Panel Fit The breaker measures 86 mm deep, 105 mm wide, and 181 mm high. These dimensions match the standard 3VA2 frame footprint; if you are replacing a 3VA2163-8HM32-0AA0 or similar sibling in the same frame size, the mounting hole pattern and bus-bar spacing are identical — no rewiring or panel modification needed.","metaTitle":"Siemens 3VA2163-0MS32-0AA0 SENTRON MCCB, 63 A, 3-Pole, ETU31","metaDescription":"Siemens 3VA2163-0MS32-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 3-pole, ETU310M trip unit.
