Its interrupting capacity hits 242 kA at 240 V AC and 187 kA at 415/440 V, dropping to 3 kA at 690 V; that 242 kA figure means it can safely clear a fault on a high-capacity transformer secondary without the arc flashing upstream. The ETU860 electronic trip unit gives adjustable N-conductor protection (OFF, 40 % to 160 % of the phase setting) and supports communication for remote monitoring — a real advantage for a distribution panel that needs to report fault events back to a BMS. ## Panel integration Mounting is via screw terminals; the 4-pole design handles three-phase plus neutral, with the N-conductor protection adjustable per the ETU860 settings. Rated insulation voltage Ui of 800 V, storage temperature range -40 °C to 80 °C, operating range -25 °C to 70 °C. The part is designed to IEC 60947-2 and carries the SENTRON brand from Siemens.","metaTitle":"Siemens 3VA2063-6KQ42-0AA0 SENTRON MCCB, 63 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-6KQ42-0AA0 molded case circuit breaker, 63 A continuous, 242 kA breaking at 240 V, ETU860 release, 4-pole.
