Its interrupting capacity reaches 242 kA at 240 V AC and 187 kA at 415/440 V, falling to 9 kA at 690 V — the high 240 V figure signals a design for low-voltage main feeders where fault current can exceed 200 kA. Maximum power loss is 162 W, which matters for enclosure ventilation planning. The breaker measures 248 mm high by 138 mm wide by 110 mm deep. Width at 138 mm is the panel cutout constraint for multi-pole mounting.","metaTitle":"Siemens 3VA2463-6HN32-0KC0 SENTRON MCCB, 630 A, 242 kA","metaDescription":"Siemens SENTRON 3VA2463-6HN32-0KC0 molded case circuit breaker, 630 A continuous at 40 °C, 242 kA breaking at 240 V. 3-pole with shunt trip and HQ aux switches.
