The 4-pole construction handles three-phase plus neutral, common in North American and some European distribution schemes where the neutral needs overcurrent protection. ## Breaking capacity — what it interrupts The interrupting ratings cover the fault-current range you'd expect on a 50 A feeder: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V. The 75.6 kA figure at 240 V means it handles high available fault current on a 240/120 V center-tapped service without series-rating coordination. At 415 V, the 52.5 kA rating covers most European industrial supply points. The TM210 thermal-magnetic release uses a fixed thermal element for overload and a magnetic trip for short-circuit — no electronic adjustment, so it's a straightforward replacement for an existing fixed-trip MCCB. The breaker measures 130 mm tall, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that occupies roughly four 18 mm pole spaces on a DIN rail. Front IP40 protects against tools and fingers; the rest of the body is open to the panel interior, so the enclosure's overall IP rating governs.","metaTitle":"Siemens 3VA1150-3ED42-0AA0 SENTRON MCCB, 50 A, 4-Pole, TM210","metaDescription":"Siemens 3VA1150-3ED42-0AA0 SENTRON molded case circuit breaker, 50 A rated at 40 °C, 4-pole, TM210 release, 75.6 kA at 240 V.

The 3VA1150-3ED42-0AA0 uses a fixed thermal-magnetic trip; the 5ED32 variant offers adjustable settings and optional communications. They share the same mounting footprint, so a panel swap is mechanical without rework, but the trip curve differs."},{"question":"How do I get pricing and availability for 3VA1150-3ED42-0AA0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm price and lead-time estimate."},{"question":"Will 3VA1150-3ED42-0AA0 drop into a panel specified around 3VA1110-5ED32-0AA0 without rewiring?","answer":"Yes, the two breakers share the same 4-pole SENTRON mounting pattern and overall dimensions (130 mm height, 101.6 mm width, 70 mm depth), so the mechanical fit is identical. The wiring terminals are in the same positions. The only difference is the trip unit — the 3VA1150-3ED42-0AA0 uses a fixed TM210 thermal-magnetic release, while the 3VA1110-5ED32-0AA0 uses an electronic release. If the original circuit required adjustable trip settings or communications, the TM210 cannot replicate those functions."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"The SENTRON 3VA series carries IEC 60947-2 certification for molded case circuit breakers. The specific compliance documentation (declaration of conformity, CE, UKCA, EAC) is available from Siemens on request. RoHS and REACH declarations are standard for current-production Siemens industrial products."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1150-3ED42-0AA0","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/3VA1150-3ED42-0AA0 when reusing this data.
