Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — figures that govern the available fault current the breaker can safely interrupt without upstream coordination failure. No communication function, phase failure detection, ground fault monitoring, or other measurement function is built in. Above that, derating applies: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. ## Panel fit and mechanical endurance A trip indicator is present.","metaTitle":"Siemens 3VA1140-5EF36-0BH0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0BH0 molded case circuit breaker, 40 A rated continuous current, 3 poles, 187 kA breaking capacity at 240 V.
