The Siemens 3VA1110-3EF32-0KA0 is a 3-pole SENTRON molded case circuit breaker rated 100 A at 40 °C, with a TM240 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. At 415 V the breaking capacity is 52.5 kA, dropping to 11.9 kA at 690 V, so verify the available fault current at your system voltage before specifying. The 100 A rating holds steady through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
