On a 480 V panel (common in North America), the 52.5 kA at 440 V is the nearest published figure — expect the actual rating at 480 V to fall between that and the 11.9 kA at 500 V. For a 400 V IEC distribution board, the 75.6 kA figure covers most high-fault scenarios. ## Thermal derating — don't size by the nameplate alone Above that, it derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If the panel ambient hits 60 °C, the breaker's effective continuous current is 96 A — not 100. Power dissipation at rated load is 25 W maximum, which matters for enclosure thermal calculations. IP40 on the front. Current production — no end-of-life notice. The 3VA platform is Siemens' active MCCB generation.","metaTitle":"Siemens 3VA1110-4FF46-0AA0 SENTRON MCCB, 4P, 100 A, TM240, 1","metaDescription":"Siemens 3VA1110-4FF46-0AA0 SENTRON molded case circuit breaker, 4-pole, 100 A rated, TM240 release, 121 kA at 240 VAC.
