100 A MCCB with TM210 trip — line protection duty
The Siemens SENTRON 3VA1010-2ED32-0AC0 is a 3-pole molded case circuit breaker rated 100 A continuous at 40 °C (Iu = 100 A), with a TM210 thermal-magnetic trip unit for line protection. Its breaking capacity reaches 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — figures that determine the available fault current it can safely interrupt at your service voltage.
The 100 A rating holds flat through 50 °C (–), then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C (–).
