The interrupting capacity tells the real story: 187 kA at 240 V and 121 kA at 415 V mean this breaker can safely clear a fault on a high-capacity transformer or a large motor starter without the arc flash escalating upstream. At 690 V the rating drops to 4.25 kA — still adequate for most 690 V distribution, but worth noting if you are feeding a high-fault industrial drive bank. The ETU350 is a microprocessor-based trip unit that provides LI (long-time and instantaneous) protection with adjustable settings. ## Thermal derating and endurance The 100 A rating holds from 40 °C up to 50 °C ambient. Above that it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. In a sealed, non-ventilated panel near a dryer section or a hot process line, that 85 A at 70 °C is the number to design against, not the catalogue 100 A. Maximum power loss is 12.5 W. For a 100 A frame that is modest — the heat stays manageable inside a standard enclosure without forced ventilation, provided you respect the ambient derating curve. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is the standard 3-pole MCCB footprint for the 3VA frame — it drops into a panel cutout or mounting plate designed for a 100 A SENTRON without re-drilling. The 86 mm depth includes the handle and the undervoltage release module; check clearance to the enclosure door if you are retrofitting into a shallow box.","metaTitle":"SENTRON 3VA2110-5HN32-0BC0 MCCB, 100 A, 187 kA IC","metaDescription":"Siemens SENTRON 3VA2110-5HN32-0BC0 molded case circuit breaker, 100 A rated, 187 kA interrupting at 240 V.
