The 20 000 mechanical endurance cycles cover routine switching for isolation or maintenance, not daily load-break duty. ## Electrical ratings and compliance context The N-conductor protection is designed at 50 %, meaning the neutral pole is rated for half the phase current, which is standard for 4-pole breakers in TN or TT systems where the neutral carries only unbalanced load.","metaTitle":"Siemens 3VA1110-6FF42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 220","metaDescription":"Siemens 3VA1110-6FF42-0AA0 SENTRON molded case circuit breaker, 100 A rated continuous current, 4-pole, TM240 release, 220 kA at 240 V.

Availability and current pricing are confirmed at quote time — no stock count or lead-time number can be stated here, but the part is a current-production item so the standard supply chain applies."},{"question":"What is the closest functional alternative to 3VA1110-6FF42-0AA0?","answer":"The 3VA1010-2ED32-0JA0 is a sibling in the same SENTRON 3VA family, but it is a 3-pole variant with a different release and lower breaking capacities. It will not drop into a 4-pole panel without rewiring the neutral conductor and verifying the fault-current rating at your voltage level."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a standard SENTRON product, it carries CE marking for the European market and is designed to meet IEC 60947-2. UL and CSA listings are typical for the 3VA series but should be confirmed against the specific variant at order time — the evidence does not list those approvals explicitly for this order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-6FF42-0AA0","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/3VA1110-6FF42-0AA0 when reusing this data.
