The Siemens 3VA1180-6EF36-0KA0 is a SENTRON molded case circuit breaker (MCCB) rated for 80 A continuous current at 40 °C, with a 220 kA breaking capacity at 240 V. The 3-pole line-protection version carries a TM240 thermal-magnetic trip unit and a built-in shunt trip (STL) release for remote opening.
At 415 V it still holds 154 kA, at 440 V it's 121 kA, and at 690 V it drops to 17 kA. The 80 A continuous rating holds steady from 40 °C up to 50 °C, then derates to 72 A at 70 °C.
