The TM120M thermal-magnetic trip unit is set for starter protection, with a rated current In of 320 A and adjustable short-circuit pickup Ii from 8 to 16 times In. This variant ships without overload protection (the TM120M provides only magnetic short-circuit protection), so it's intended for use in combination with a separate overload relay or motor protection device upstream. Two auxiliary switch changeover contacts are built in, so you can signal the breaker status to a PLC or annunciator without adding external contact blocks.","metaTitle":"Siemens 3VA1332-6MH32-0AB0 Circuit Breaker, 3VA1 IEC Frame 4","metaDescription":"Siemens 3VA1332-6MH32-0AB0 circuit breaker, 3VA1 IEC frame 400, breaking capacity class H, Icu=70kA @ 415V, 3-pole, starter protection TM120M, In=320A, short-circuit protection Ii=","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=1528223&mlfb=3VA1332-6MH32-0AB0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1332-6MH32-0AB0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA1332-6MH32-0AB0 and get a price?","answer":"We source this part to order against an RFQ.
