This variant is configured for starter protection with a TM120M thermal-magnetic trip unit, but note the description explicitly states it provides short-circuit protection only — no overload protection is included. The short-circuit pickup Ii is adjustable 5 to 15 x In (315 A to 945 A). Mounts on standard DIN rail or panel-mount within the 3VA1 enclosure family. ## Integration Notes The 3VA1 frame accepts plug-in accessories like auxiliary contacts, shunt trips, and alarm switches — the UVR here occupies one accessory slot. Verify the nut keeper kit is installed before torquing busbar connections; it prevents hardware migration under vibration. At 63 A on a 160 A frame, thermal rise is well within limits — the larger frame gives headroom for higher ambient temperatures or enclosed panel mounting without derating concerns. The class H breaking capacity (70 kA @ 415 V) exceeds typical 25-50 kA requirements for most industrial distribution, so selectivity coordination with downstream breakers is straightforward.","metaTitle":"Siemens 3VA1163-6MH32-0CA0 Circuit Breaker, 63A, 70kA @ 415V","metaDescription":"Siemens 3VA1163-6MH32-0CA0 circuit breaker, IEC frame 160, breaking capacity class H, Icu=70kA @ 415V AC, 3-pole, starter protection TM120M, In=63A, undervoltage release 120-127V A","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=470563&mlfb=3VA1163-6MH32-0CA0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1163-6MH32-0CA0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of 3VA1163-6MH32-0CA0?","answer":"The breaking capacity class H gives an Icu of 70 kA at 415 V AC.
