The Siemens SENTRON 3VA1010-2ED32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. It delivers a breaking capacity of 52.5 kA at 240 V AC, stepping down to 32 kA at 415 V and 13.6 kA at 440 V — numbers that matter when coordinating downstream with a transformer secondary or a motor control center.
Full 100 A rating holds up to 50 °C ambient. Above that the curve is gradual: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C.
The 52.5 kA at 240 V is the headline number, but the real-world selectivity study uses the 415 V figure (32 kA) for common distribution voltages. At 690 V the breaker still clears 7.5 kA — enough for most 690 V drives, provided the fault current doesn't exceed that.
