The interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — numbers that cover high-fault commercial and industrial service entrances. IP40 on the front; the rest of the enclosure is panel-side. ## Thermal derating and continuous current Above that the curve drops: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. Width 76.2 mm (three-pole), depth 70 mm, height 130 mm. The IP40 front rating means the operator face is protected against tools and fingers; the rest relies on the enclosure seal.","metaTitle":"Siemens 3VA1140-5EF36-0AG0 SENTRON MCCB, 40 A, 3-pole, 187 k","metaDescription":"Siemens 3VA1140-5EF36-0AG0 SENTRON molded case circuit breaker, 40 A, 3-pole, interrupting capacity 187 kA at 240 V.
