Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V. For a 400 V distribution board, the 121 kA figure covers most high-fault scenarios. ## Panel integration and dimensions The 3VA2 frame measures 110 mm deep, 138 mm wide, and 248 mm tall. That 138 mm width for a 3-pole 630 A MCCB is compact for the rating — it fits standard panel cutouts and leaves room for cable entry. ## Auxiliary functions and compliance Undervoltage release (UVR) is fitted. Ground fault monitoring uses summation current formation on the L-conductor. Latching endurance is 15,000 operations. Siemens provides RoHS, REACH, UL, and IEC compliance documentation for the SENTRON series.","metaTitle":"Siemens 3VA2463-5JQ32-0BC0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens 3VA2463-5JQ32-0BC0 SENTRON molded case circuit breaker, 630 A at 40 °C, 3-pole, line protection with ETU560 release. 187 kA at 240 V.
