It's built for line protection — main feeder or large branch circuit — in commercial and industrial panels. The interrupting capacity hits 75.6 kA at 240 V AC, tapering to 7.5 kA at 690 V, so it handles high available fault current at common distribution voltages without cascading upstream. No separate auxiliary release to buy and install. Above that it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, stepping down to 36 A at 70 °C. ## Mounting and fit","metaTitle":"Siemens 3VA1040-3ED36-0DA0 SENTRON MCCB, 3-pole 40 A, TM210,","metaDescription":"Siemens SENTRON 3VA1040-3ED36-0DA0 molded case circuit breaker, 3-pole, 40 A at 40 °C, TM210 release, high interrupting capacity (75.6 kA at 240 V).
