That 63 A is the rated continuous current (, –), so it handles a full-load motor current up to that value without nuisance tripping on a warm cabinet floor. The ETU860M electronic trip unit gives you adjustable trip classes: 10A, 10/10E, 20/20E, and 30/30E. That range covers everything from fast-clearing on short-cyclic loads (class 10A) to slower curves for high-inertia starts (class 30/30E). Phase failure detection and a ground-fault monitoring version using summation current formation on the L-conductor are built in — the breaker watches for a lost phase or leakage path without needing an external relay. The 690 V rating covers the higher-voltage distribution side where fault currents are lower but arc energy is greater. Dimensions: 86 mm depth, 105 mm width, 181 mm height (–).","metaTitle":"Siemens 3VA2163-0MQ32-0AA0 SENTRON MCCB, 63 A, 440 kA at 415","metaDescription":"Siemens 3VA2163-0MQ32-0AA0 SENTRON molded case circuit breaker, 63 A continuous, 440 kA breaking at 415 V.
