It carries a 440 kA interrupting rating at 240 V and 330 kA at 415 V, with the rating dropping to 52.5 kA at 690 V. The ETU330 trip unit handles LSIG (long-time, short-time, instantaneous, ground-fault) curves, and the ground-fault monitoring is summation-current on the line conductors. That matters for a solidly-grounded system where you want a single device to cover phase and ground protection without an external relay. The 3VA2463-8HM32-0AA0 measures 138 mm wide, 248 mm high, and 110 mm deep. That's a standard SENTRON 3VA frame footprint — it bolts into a panel on a mounting plate, not a DIN rail.","metaTitle":"Siemens 3VA2463-8HM32-0AA0 SENTRON MCCB, 630 A, 3-pole, ETU3","metaDescription":"Siemens SENTRON 3VA2463-8HM32-0AA0 molded case circuit breaker, 630 A at 40 °C, 3-pole, ETU330 electronic trip, 440 kA at 240 V.
