That 40 A rating is the load-side limit; the breaker frame itself is rated for a maximum of 480 A and a minimum setting of 60 A, so the ETU320 is set at the low end of the frame's capability. The 242 kA interrupting capacity at 240 V and 187 kA at 415 V means this breaker safely clears high-fault currents without cascading upstream — a key figure for selectivity studies in distribution panels where the available fault current is known to exceed 100 kA. ## Integration and panel fit The breaker occupies 140 mm width, 181 mm height, and 86 mm depth. The ETU320 trip unit is an electronic overcurrent release with no communication function and no ground-fault monitoring; it provides adjustable long-time, short-time, and instantaneous protection settings via DIP switches or rotary dials on the front face. No undervoltage release and no voltage trigger are fitted, so any undervoltage or shunt-trip function must be added externally if required.","metaTitle":"Siemens 3VA2040-6HL46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 242 k","metaDescription":"Siemens 3VA2040-6HL46-0AA0 SENTRON molded case circuit breaker, 40 A rated, 4-pole, ETU320 release, 242 kA SCCR at 240 V.

Submit a request for quote (RFQ) to confirm availability and current pricing — no stock count or price is listed here, but the channel can provide a firm quote with lead time at the time of inquiry."},{"question":"What is the closest functional second-source for 3VA2040-6HL46-0AA0?","answer":"The closest peer within the same SENTRON 3VA2 frame is 3VA2040-8HN42-0AA0. Both share the 40 A continuous rating, 4-pole configuration, and ETU320 trip unit. The primary difference is the interrupting capacity: the -6HL46-0AA0 carries 242 kA at 240 V, while the -8HN42-0AA0 is rated for a lower SCCR. Verify the available fault current at your installation before substituting."},{"question":"What is 3VA2040-6HL46-0AA0's listed depth (86 mm) on this component line?","answer":"The depth is 86 mm, measured from the mounting surface to the front of the breaker. This is the dimension that governs enclosure depth clearance."},{"question":"What is 3VA2040-6HL46-0AA0's listed width (140 mm) on this component line?","answer":"The width is 140 mm, which determines the panel cutout or DIN-rail spacing required for installation."},{"question":"Will 3VA2040-6HL46-0AA0 drop into a panel that was specified around 3VA2040-8HN42-0AA0 without rewiring?","answer":"Yes, the two breakers share the same frame size (140 mm width, 181 mm height, 86 mm depth) and the same 4-pole footprint. No rewiring is required for the mechanical fit. However, the interrupting capacity differs — verify that the available fault current at the installation does not exceed the lower-rated peer's capability before swapping."},{"question":"What compliance documentation does this brand provide for 3VA2040-6HL46-0AA0 (RoHS, REACH, UL, IEC)?","answer":"As a SENTRON product, the 3VA2 series typically carries UL 489, IEC 60947-2, and CSA C22.2 No. 5 certifications, along with RoHS and REACH compliance declarations. Specific documentation for this order code should be available from the manufacturer's technical support portal or requested at the time of RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2040-6HL46-0AA0","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/3VA2040-6HL46-0AA0 when reusing this data.
