The Siemens 3VA2110-7MS36-0CC0 is a SENTRON molded case circuit breaker (MCCB) in the starter protection product version, rated for a continuous current Iu of 100 A across a 40 °C to 50 °C ambient band — it holds 100 A flat through that range, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. That thermal profile means the breaker can be installed in a warm panel without oversizing, as long as the ambient stays under 50 °C at full load. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. It is a 3-pole unit with an ETU310M electronic overcurrent release. The 'M' suffix on the release designates motor / starter protection characteristics, meaning it provides the Class 10 or Class 20 overload curve needed for motor starting inrush without nuisance tripping.
Built-in auxiliary and undervoltage release
The auxiliary switches are wired for status feedback — open/closed indication to a PLC or status lamp. The integrated auxiliary trip is 3VA9608-0BB24 — these are the internal sub-assembly order codes if you need replacement parts.
Physical dimensions: 181 mm height, 105 mm width, 86 mm depth — standard SENTRON 3VA2 frame size.
