What this MCCB brings to a panel
The Siemens 3VA1110-5ED26-0AA0 is a 2-pole SENTRON molded case circuit breaker rated 100 A continuous at 40 °C, with a TM210 thermal-magnetic release. The IP40 front rating means it's fine inside a panel enclosure; no washdown capability here.
Thermal derating — the real-world current
This breaker holds its full 100 A rating up through 50 °C ambient. At 55 °C it derates to 98 A, at 60 °C to 96 A, and at 70 °C to 91 A.
The 3VA1110-5ED26-0AA0 measures 70 mm deep, 50.8 mm wide, and 130 mm tall. That 2-inch width is the standard 2-pole MCCB footprint — it drops into the same panel cutout and bus-bar spacing as other 2-pole SENTRON frames. No need to re-drill or re-bus a panel that was laid out for a 3VA1 family breaker.
