Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V — figures that place it in the high-fault tier of the 3VA family, sized for main feeders or large sub-distribution where available fault current exceeds 200 kA. Above that, derate linearly: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. The enclosure measures 248 mm high, 184 mm wide, and 110 mm deep — a 4-pole footprint that fits standard SENTRON mounting patterns. Front-side IP40 protection means it is suited for enclosed panel mounting where splash or dust ingress is not a concern. The ETU340 release offers adjustable long-time, short-time, instantaneous, and ground-fault protection curves, which is what makes it a line-protection device rather than a basic thermal-magnetic. No undervoltage release, no communication module, and no ground-fault monitoring version are fitted on this order code.","metaTitle":"Siemens 3VA2463-7HK42-0AA0 SENTRON MCCB, 630A, 4-Pole, 330kA","metaDescription":"Siemens SENTRON 3VA2463-7HK42-0AA0 molded case circuit breaker, 630A continuous, 4-pole, 330kA interrupting at 240V.
