Thermal derating is built into the spec: the breaker carries 630 A at 40 °C, 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 ETU350 trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves. The SENTRON 3VA platform is Siemens' current-generation MCCB family, replacing the earlier 3VL series. The 3VA2463-0HN32-0DF0 is a full-size frame (138 mm wide, 248 mm tall, 110 mm deep) — panel cutout and busbar spacing follow the 3VA frame footprint, not the older 3VL. ## Integration and compliance notes The storage minimum matters for unheated warehouses in cold climates — the breaker can be stored at -40 °C but must be warmed above -25 °C before energizing.","metaTitle":"Siemens 3VA2463-0HN32-0DF0 SENTRON MCCB, 630A, 440kA at 415V","metaDescription":"Siemens SENTRON 3VA2463-0HN32-0DF0 molded case circuit breaker, 630A, 3-pole, ETU350 trip unit, 440 kA at 415 V.
