It is rated for line protection with a TM240 thermal-magnetic trip unit, set for a 20 A nominal current (In) with overload protection adjustable from 14 A to 20 A (Ir). Short-circuit protection (Ii) is fixed at 8 to 16 times In. The nut keeper kit keeps the terminal hardware captive during wiring — a small detail that saves time on repetitive builds. Rated for IEC 60947-2 compliance, it is suited for main or branch-circuit protection in industrial switchgear where the 55 kA interrupting rating at 415 V provides headroom for high-fault installations.","metaTitle":"3VA1120-5EF32-0AA0-ZD00 Siemens 3VA1 20A MCCB, 55kA @ 415V","metaDescription":"Siemens 3VA1120-5EF32-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, 20A, Icu=55kA @ 415V, TM240 overload, active lifecycle, quoted 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=1667637&mlfb=3VA1120-5EF32-0AA0-ZD00","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1120-5EF32-0AA0-ZD00/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of this MCCB?","answer":"The Icu (ultimate breaking capacity) is 55 kA at 415 V AC, class M.
