Its interrupting capacity reaches 330 kA at 240 V and 242 kA at 415 V, which means it can safely clear very high fault currents typical of large transformer secondaries or bus-duct feeds without cascading upstream — the kind of SCCR headroom a site electrical engineer needs for a selective coordination study. The breaker carries a 20 000-cycle mechanical endurance, so it holds up in frequent-switching applications like pump or compressor panels where the disconnect is cycled daily. The auxiliary contact configuration is 2 auxiliary switches plus 1 trip alarm and 1 electrical alarm switch (HQ type), giving the PLC or BMS four discrete status points: open/closed, tripped on fault, and a separate electrical alarm signal. The breaker holds its full 63 A rating up to 50 °C ambient; above that it derates linearly to 53.55 A at 70 °C. In a sealed, non-ventilated enclosure the panel builder should account for the 6.5 W maximum power loss when sizing internal temperature rise. Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard SENTRON 3VA footprint that drops into existing DIN-rail or screw-mount panel layouts without re-drilling.","metaTitle":"Siemens 3VA2163-7HN32-0CL0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7HN32-0CL0 molded case circuit breaker, 63 A, 3-pole, ETU350 release, 330 kA at 240 V.

The difference is the trip unit: the -7HN32-0CL0 uses an ETU350 electronic release, while the -5HL32-0DB0 uses a different release variant. Check the trip settings and auxiliary contact wiring before swapping — the undervoltage release and auxiliary contact configuration may differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2163-7HN32-0CL0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2163-7HN32-0CL0 when reusing this data.
