The insulation voltage is rated at 800 V, so it's comfortable on 480 V or 600 V class systems. The trip indicator is absent — you'd rely on the auxiliary switch feedback or handle position for status. Rated current holds flat at 100 A from 40 °C up to 50 °C — useful if the panel runs warm but not hot. Above that it derates gradually: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That thermal curve is well-documented, so you can size the breaker without guesswork if the ambient in your enclosure pushes past 40 °C. Mechanical footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB envelope that fits most DIN-rail or panel-mount enclosures without re-drilling. Storage range spans -40 °C to 80 °C, and operating ambient goes from -25 °C to 70 °C — the storage limit is about handling, not running.","metaTitle":"Siemens SENTRON 3VA1110-4EF32-0CC0 MCCB, 100A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0CC0 molded case circuit breaker, 3-pole, 100A rated at 40°C, 121 kA breaking capacity at 240 VAC.
