At 240 V it interrupts 187 kA; at 415 V and 440 V it holds 121 kA, dropping to 75.6 kA at 500 V and 9 kA at 690 V. The 3-pole footprint matches the existing 3VA family cutout; if you're swapping an older 3VA2116 frame, verify the lug kit and accessory compatibility (the ETU320 shares the same communication and auxiliary-contact platform). ## What the ETU320 trip unit gives you The ETU320 is an electronic overcurrent release — no thermal bimetal, so trip curves stay consistent across ambient shifts. It's designed for line protection (cable and busbar), not motor or generator protection. There's no ground-fault monitoring version on this variant, no undervoltage release, and no communication function. If you need those, the 3VA family has sibling order codes with those options; this one is a straight feeder breaker with adjustable LS (long-time and short-time) pickup and delay settings via the trip unit dials.","metaTitle":"Siemens 3VA2440-5HL32-0AA0 SENTRON MCCB, 400 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, ETU320 electronic trip.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time on your quantity."},{"question":"What is the closest functional second-source to 3VA2440-5HL32-0AA0?","answer":"The closest sibling in the same SENTRON 3VA family is the 3VA2116-5HL32-0AK0, but that's a lower-current frame (160 A vs. 400 A). It shares the same ETU320 trip platform and 3-pole form factor, so the accessory ecosystem (auxiliary contacts, shunt trips, communication modules) is identical. For a 400 A feeder, the 3VA2440 is the correct frame; the 3VA2116 won't carry the load."},{"question":"Will 3VA2440-5HL32-0AA0 drop into a panel specified around 3VA2116-5HL32-0AK0 without rewiring?","answer":"No — the 3VA2440 frame is physically larger (248 x 138 x 110 mm vs. the 3VA2116's smaller dimensions) and rated for 400 A vs. 160 A. The mounting hole pattern and busbar spacing differ. You'd need to rework the panel cutout and bus connections."},{"question":"What compliance documentation does this breaker carry?","answer":"As a Siemens SENTRON product, it carries IEC 60947-2 certification for molded case circuit breakers. RoHS and REACH compliance documentation is available from Siemens. The 800 V rated insulation voltage and the SCCR ratings at multiple voltage levels (187 kA at 240 V, 121 kA at 415 V, 9 kA at 690 V) are verified per IEC 60947-2 test conditions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2440-5HL32-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2440-5HL32-0AA0 when reusing this data.
