The interrupting ratings climb to 440 kA at 240 V and 330 kA at 415/440 V, tapering to 52.5 kA at 690 V. The trip unit has a 20 A minimum setting and a 100 A full-scale value, so it's field-adjustable for a range of feeder or branch loads without swapping the breaker. Ground-fault monitoring works via summation current formation on L+N, and the communication function is built in — no separate module required for status or remote trip signalling. Power loss runs 7.7 W at full load. ## Sizing and selectivity The adjustable trip range (150–1,200 A) lets you set it for a 150 A feeder or crank it up for a 1,200 A main, but the continuous current rating of 100 A is the hard limit for the frame and lugs. If your load draws more than 100 A steady, you need a larger frame. The 4-pole construction means it switches all three phases plus neutral, which is standard for North American 120/208 V or 277/480 V wye systems where you need the neutral switched or monitored. ## Physical fit That's a standard MCCB footprint for the 100 A frame size — it'll drop into a 4-pole mounting base or panel cutout without surprises.","metaTitle":"Siemens 3VA2110-8JQ42-0AA0 SENTRON MCCB, 100 A, 150–1200 A T","metaDescription":"Siemens SENTRON 3VA2110-8JQ42-0AA0 molded case circuit breaker, 4-pole, 100 A continuous, adjustable trip 150–1200 A, 440 kA at 240 V.

The key difference is the trip range: this breaker adjusts from 150 A to 1,200 A, while the 3VA2163 variant uses a different trip unit. If the existing panel's wiring and bus bars are sized for a 100 A continuous frame, the swap is mechanical — no re-drilling or re-bussing needed. But verify the trip curve and settings match your protection coordination study before swapping."},{"question":"What compliance documentation does this brand provide for 3VA2110-8JQ42-0AA0 (RoHS, REACH, UL, IEC)?","answer":"As a Siemens SENTRON product, this MCCB carries CE marking for the European market and is designed to IEC 60947-2. UL and CSA listings are standard for the 3VA family, and RoHS/REACH declarations are available from Siemens' documentation portal. Specific certification marks for this exact order code should be confirmed from the manufacturer's declaration of conformity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2110-8JQ42-0AA0","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/3VA2110-8JQ42-0AA0 when reusing this data.
