For a motor branch circuit or a feeder in a 415 V industrial distribution board, that's the figure that governs whether the breaker holds or fails on a bolted fault. The TM120M trip is starter-protection style — it's a thermal-magnetic curve tuned for motor starting inrush, with an adjustable magnetic pickup (Ii) from 5 to 15 times In. At the 100 A rating, that gives a short-circuit pickup range of 500 A to 1500 A. That's tighter than a standard distribution curve, so it coordinates better with a contactor and overload relay downstream. But note: this order code ships without overload protection — the thermal element is present in the TM120M, but the description flags 'without overload protection', meaning the thermal function may be disabled or the breaker is intended as a short-circuit protector only, paired with a separate overload relay. The shunt trip (STL) operates on 220-250 V DC or 208-277 V AC. That covers common control voltages in North American (277/480 V) and European (230/400 V) panels. The two HQ auxiliary switches plus one HQ trip alarm switch give remote status of the breaker position and fault condition — enough for a PLC to know whether the breaker is open, closed, or tripped on fault.","metaTitle":"Siemens 3VA1110-6MH32-0KH0 Circuit Breaker, 70kA @ 415V, 100","metaDescription":"Siemens 3VA1110-6MH32-0KH0 IEC frame 160 MCCB, 70kA breaking capacity @ 415V, 100A TM120M, shunt trip, aux switches, current lifecycle stage, sourced to order.","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=375380&mlfb=3VA1110-6MH32-0KH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1110-6MH32-0KH0/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this breaker?","answer":"It is rated Icu = 70 kA at 415 V AC, which is the class H breaking capacity for the 3VA1 IEC frame 160 range."},{"question":"What does the shunt trip require for voltage?","answer":"The shunt trip (STL) operates on 220-250 V DC or 208-277 V AC, covering common control voltages in both 50 Hz and 60 Hz panels."},{"question":"Where can I buy the 3VA1110-6MH32-0KH0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
