It delivers 121 kA interrupting capacity at 240 V AC and 75.6 kA at 415 V AC — figures that cover most industrial service-entrance and feeder applications without needing an upstream current-limiting fuse. The compact 50.8 mm wide footprint fits standard panel layouts, and the IP40 front protection suits enclosed distribution boards. Current rating holds flat at 40 A from 40 °C through 50 °C, then steps down to 39 A at 55–60 °C, 38 A at 65 °C, and 37 A at 70 °C (–). Maximum power loss is 7.2 W.","metaTitle":"Siemens 3VA1140-4ED26-0AA0 SENTRON MCCB, 40 A, 2-Pole, 121 k","metaDescription":"Siemens 3VA1140-4ED26-0AA0 SENTRON molded case circuit breaker, 40 A, 2-pole, TM210 release, 121 kA at 240 V AC.
