It interrupts up to 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — the 690 V figure tells you this breaker holds up on 600 V class systems where many MCCBs derate hard. Current rating holds flat at 100 A from 40 °C up to 50 °C, then tapers to 91 A at 70 °C — so in a hot panel near the mill roof or a drive cabinet you still get 91 A without tripping. The 75.6 kA interrupting rating at 240 V gives headroom for high-fault industrial services; at 415 V it still clears 52.5 kA, enough for most distribution transformers. ## Panel integration","metaTitle":"Siemens 3VA1110-3EF36-0AC0 SENTRON MCCB, 100 A, 75.6 kA at 2","metaDescription":"Siemens 3VA1110-3EF36-0AC0 SENTRON molded case circuit breaker, 100 A rated at 40 °C, 75.6 kA interrupting at 240 V.

The difference is the release: the 3EF36 uses a TM240 thermal-magnetic trip (fixed), while the 5ED36 uses an electronic release. If the panel wiring and load current match the 100 A rating, the 3EF36 fits mechanically without rewiring — but check the trip curve coordination if the original design relied on electronic adjustment."},{"question":"What compliance documentation does this brand provide for 3VA1110-3EF36-0AC0?","answer":"Siemens SENTRON breakers are typically supplied with a CE declaration of conformity and a UL/CSA listing mark on the nameplate. RoHS and REACH compliance declarations are available from Siemens on request. No specific certificate numbers are listed in this record, but the brand standard is to include them with the shipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-3EF36-0AC0","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/3VA1110-3EF36-0AC0 when reusing this data.
