It uses an ETU320 electronic trip unit with LI (long-time and instantaneous) protection. The continuous current rating In is 400 A; the long-time pickup Ir is adjustable from 160 A to 400 A, and the instantaneous pickup Ii is adjustable from 1.5 to 10 times In. It includes a left-mounted shunt trip for 208–277 V AC 50/60 Hz or 220–250 V DC, plus one auxiliary switch (changeover contact). A nut keeper kit is also included. ## Where this breaker fits in a panel This is a fixed (non-withdrawable) MCCB designed for DIN-rail or panel-mount installation in a distribution board or motor control center. The 3VA2 frame 400 footprint is standard across the series, so busbar connections and enclosure cutouts are shared with other 3VA2 400 A units. The left-mounted shunt trip and auxiliary switch occupy accessory slots; verify wiring clearance on the left side of the breaker before laying out the gland plate.","metaTitle":"Siemens 3VA2340-5HL32-0KK0 3VA2 IEC Frame 400, 55kA @ 415V,","metaDescription":"Siemens 3VA2340-5HL32-0KK0 circuit breaker, 3VA2 IEC frame 400, breaking capacity class M, Icu=55kA @ 415V, 3-pole, ETU320 LI, In=400A, Ir=160A-400A, Ii=1.5-10xIn, shunt trip left","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":"https://cdn.aoctrl.com/c1b3b6c5f6d67465025ac41848ceb75e.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1437122&mlfb=3VA2340-5HL32-0KK0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2340-5HL32-0KK0/alternatives.json"},"ai":{"faq":[{"question":"What is the interrupting rating of this breaker?","answer":"The breaking capacity class M gives Icu = 55 kA at 415 V AC, 3-pole."},{"question":"What trip unit and adjustments does this breaker have?","answer":"It uses an ETU320 electronic trip unit with LI protection.
