Its interrupting capacity hits 75.6 kA at 240 V AC and 9 kA at 415 V AC — that 75.6 kA figure is the one that matters for high-fault panels fed from a large transformer, where the available short-circuit current can exceed what a standard MCB handles. Rated operating voltage is 415 V AC and 125 V DC, so it covers single-phase line protection and some DC tap circuits. The 25.4 mm width (1 inch) means it snaps into a standard MCCB panel slot without needing a wider cutout. ## Thermal derating and what the TM210 release means The TM210 designation tells you the thermal element is fixed at 40 A (the '210' code indicates a 40 A rating in the 3VA naming convention). Continuous current holds at 40 A from 40 °C up to 50 °C, then drops to 39 A at 55 °C and 60 °C, 38 A at 65 °C, and 37 A at 70 °C. ## Panel integration and environmental limits The 70 mm depth (2.76 in) is standard for the 3VA 1-pole form factor, so it fits existing 3VA panel layouts without a gland-plate change.","metaTitle":"3VA1140-4ED12-0AA0 SENTRON MCCB, 1-pole, 40 A, TM210, 75.6 k","metaDescription":"SENTRON 3VA1140-4ED12-0AA0 1-pole MCCB, 40 A rated at 40 °C, TM210 release, 75.6 kA breaking at 240 V AC.
