It is specifically designed for motor protection, with integrated phase failure detection and adjustable short-time delay settings (minimum 4 s, maximum 17 s) that let you coordinate with downstream motor starters and upstream feeders. The interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — these numbers define the maximum fault current the breaker can safely clear at each voltage level, which is the primary spec for panel SCCR compliance. The 100 A frame is flat-rated across temperature, so you don't lose capacity in a warm enclosure. ## Motor protection design — what that means for your line This breaker is built for motor protection, not just cable protection. The phase failure detection catches a lost phase before the motor overheats. It ships with the basic switch 3VA21105MN320AA0 as the switching mechanism. If you need remote trip or ground-fault, you add external modules. The breaker measures 181 mm high, 105 mm wide, and 86 mm deep (7.13 x 4.13 x 3.39 inches). That 105 mm width for a 3-pole 100 A frame is standard for SENTRON 3VA2 breakers — it will drop into the same mounting footprint as other 3VA2 100 A units. The depth of 86 mm includes the arc chamber and terminals; allow clearance for cable bending radius below the line and load lugs.","metaTitle":"Siemens 3VA2110-5MN32-0AC0 SENTRON MCCB, 100A, 3-Pole, Motor","metaDescription":"Siemens SENTRON 3VA2110-5MN32-0AC0 molded case circuit breaker, 100A continuous, 3-pole, motor protection design with phase failure detection.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment."},{"question":"What is the interrupting capacity of 3VA2110-5MN32-0AC0 at 480V?","answer":"The evidence lists interrupting capacities at 415 V (121 kA), 440 V (121 kA), and 500 V (75.6 kA). For 480 V, the value would fall between the 440 V and 500 V figures — expect approximately 100 kA, but verify with the manufacturer's published curves for your specific system voltage."},{"question":"Will 3VA2110-5MN32-0AC0 drop into a panel specified around 3VA2116-5JP32-0AE0 without rewiring?","answer":"Both are 3-pole SENTRON 3VA2 breakers in the same frame size, so the mounting footprint and bus-bar spacing are identical. The 3VA2110-5MN32-0AC0 is a 100 A motor-protection breaker; the 3VA2116-5JP32-0AE0 is a different rating. Check the load current and protection curve — if the 100 A rating matches your load, it is a direct mechanical swap. No rewiring of the bus bars or DIN-rail mounting is needed."},{"question":"What compliance documentation does Siemens provide for 3VA2110-5MN32-0AC0?","answer":"As a standard SENTRON MCCB, this breaker carries CE marking for the European market and is designed to IEC 60947-2. UL/CSA listings are typical for the 3VA series but should be confirmed against the specific variant. RoHS and REACH declarations are available from Siemens' documentation portal for the 3VA2 family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2110-5MN32-0AC0","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/3VA2110-5MN32-0AC0 when reusing this data.
