The Siemens SENTRON 3VA1110-5ED22-0AA0 is a 2-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously at 40 °C and holding that rating flat through 50 °C before a gentle derate curve — 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That means in a warm panel you keep nearly full ampacity; no need to oversize for a 50 °C ambient. The TM210 thermal-magnetic release is fixed, non-interchangeable, tuned for line protection duty.
At 70 mm deep, 50.8 mm wide, and 130 mm tall, this 2-pole MCCB fits standard SENTRON 3VA panel footprints. Ground-fault monitoring is not included. The neutral conductor is not upgradeable.
