The integrated undervoltage release (UVR) means the breaker drops on loss of control voltage — common in safety circuits or remote E-stop strings. Three poles, line protection version, no ground-fault module on this variant. Physical fit: 105 mm wide, 181 mm tall, 86 mm deep — standard 3-pole MCCB footprint for a 63 A frame. Power loss maxes at 7.9 W, which matters for thermal rise inside a sealed enclosure. ## Breaking capacity across voltages — selectivity planning This breaker's interrupting rating drops as voltage rises: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V. The undervoltage release (UVR) is factory-installed — verify the control voltage matches your system before wiring. The auxiliary contact block (2 NO/NC + 1 alarm) is pre-populated; no separate purchase needed for basic status feedback. The ETU350 trip unit is adjustable via rotary dials on the front face — set the long-time pickup (Ir), short-time pickup (Sd), and instantaneous (Ii) per your coordination study before closing the panel. Derate the continuous current above 55 °C: at 70 °C it's 53.55 A, not 63 A.","metaTitle":"Siemens 3VA2063-6HN32-0DH0 SENTRON MCCB, 63 A, 242 kA at 240","metaDescription":"Siemens 3VA2063-6HN32-0DH0 SENTRON molded case circuit breaker, 3-pole, 63 A rated, 242 kA breaking at 240 V.
