Its interrupting capacity reaches 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault scenarios typical of large industrial feeders or transformer secondaries without needing an upstream current-limiting fuse. ## Thermal derating and trip unit The 630 A rating holds at 40 °C ambient; at 70 °C it derates to 520 A. The ETU350 electronic trip gives adjustable long-time, short-time, instantaneous, and ground-fault protection curves, so you can coordinate selectivity downstream without swapping trip units. Dimensions are 248 mm high, 138 mm wide, 110 mm deep. Two auxiliary switches (HQ type) are built in for status feedback to the PLC or annunciator.","metaTitle":"Siemens SENTRON 3VA2463-6HN32-0AC0 MCCB, 630A, 242kA at 240V","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0AC0 molded case circuit breaker, 630 A rated, 242 kA interrupting at 240 V.
