The breaker carries a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — these ratings govern the available fault current the device can safely interrupt at each system voltage, which is the primary selection criterion for coordination studies. Above 55 °C the current must be reduced: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. ## Auxiliary and trip configuration The integrated auxiliary trip uses order code 3VA9688-0BL33. A voltage trigger is present, and a trip indicator gives local visual confirmation of a tripped state.","metaTitle":"Siemens 3VA1180-3EF32-0KH0 SENTRON MCCB, 80 A, 3-Pole, 70 mm","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0KH0 molded case circuit breaker, 80 A rated continuous current, 3-pole, line protection with TM240 release.
