The Siemens 3VA1010-2ED42-0KA0 is a 4-pole SENTRON molded case circuit breaker rated for 100 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. The interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so at 415 V it clears faults up to 32 kA without upstream coordination issues, but at 690 V the 7.5 kA limit means the available fault current at that voltage must be checked against the panel's SCCR. The 100 A rating holds steady through 50 °C; above that it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. This is a line-protection breaker (not a motor-protection or ground-fault device), so it's sized for feeder or branch-circuit overcurrent protection in distribution panels. The shunt trip (STL) allows remote tripping via a separate control signal, and the auxiliary trip accessory (3VA9688-0BL33) can be added for status feedback.
The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint for a 100 A frame.
