The 3-pole design with integrated phase failure detection means it catches a lost phase on a three-phase motor load and trips before single-phasing cooks the winding. Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — that 187 kA at 240 V is high enough for most industrial main feeders; the 121 kA at 415 V covers heavy distribution panels downstream of a large transformer. The trip indicator gives a visual flag after a fault event, so a tech walking the line sees which breaker popped without opening the door. That 105 mm width across three poles is standard for a 63 A frame — fits a typical MCC bucket or distribution panel without crowding.","metaTitle":"Siemens SENTRON 3VA2163-5MN32-0AJ0 MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2163-5MN32-0AJ0 molded case circuit breaker, 63 A continuous, 3-pole, motor protection design with phase failure detection.
