Breaking capacity drops as system voltage rises: 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The high 187 kA at 240 V makes this breaker a strong candidate for 240 V delta or split-phase high-fault panels where a standard 65 kA or 100 kA MCCB would not coordinate. ## Thermal derating and power dissipation Above that, derate continuously: 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. If this breaker sits in a warm enclosure or near other heat sources, use the 50 °C or 60 °C column for your actual load — a 630 A fan motor on a 50 °C panel sees only 593 A available before the trip unit responds. Maximum power loss is 162 W at rated current, which factors into enclosure ventilation sizing. The ETU350 electronic trip unit provides LSIG (long-time, short-time, instantaneous, ground-fault) protection with adjustable settings — typical for selective coordination in distribution downstream of a main breaker. The shunt trip (STL) allows remote tripping via a control signal, useful for emergency-stop or fire-safety interlocks. If remote undervoltage protection or Modbus/Profibus monitoring is needed, the 3VA2 platform supports those as separate option modules — but this order code does not carry them built in. ## Physical dimensions and mounting Dimensions: 248 mm height, 138 mm width, 110 mm depth. Depth at 110 mm is shallow enough for most 400 mm deep enclosures with wiring space behind.","metaTitle":"Siemens 3VA2463-5HN32-0JC0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2463-5HN32-0JC0 molded case circuit breaker, 630 A rated, 187 kA breaking at 240 V.
