The TM240 release provides an adjustable long-time pickup (Ir) up to 1000 A and a fixed magnetic instantaneous trip. ## Interrupting capacity — where it clears faults This MCCB delivers 121 kA interrupting capacity at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. ## Thermal derating — what 100 A means at panel ambient Above that, derating kicks in: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Plan the load at 91 A if the enclosure ambient hits 70 °C, not the nameplate 100 A. Maximum power loss is 25 W. That's the heat the breaker dumps into the panel at full rated current — a factor for enclosure thermal calculations, especially in sealed cabinets. The 4-pole width of roughly 4 inches (101.6 mm) is standard for this frame size.","metaTitle":"Siemens 3VA1110-4EF46-0AA0 SENTRON MCCB, 100 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1110-4EF46-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, TM240 release.

The difference is the release: this one carries a TM240 thermal-magnetic release rated 100 A, while the 3VA1010-2ED32-0JA0 uses a different release. Wiring and bus connections are the same; the swap depends on whether the trip curve and ampacity match the circuit design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-4EF46-0AA0","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/3VA1110-4EF46-0AA0 when reusing this data.
