SENTRON 3VA1140-6ED36-0AA0 — 40 A MCCB, Line Protection, TM210 Release
It carries a 220 kA breaking capacity at 240 V and 154 kA at 415 V, with a TM210 thermal-magnetic overcurrent release.
Breaking capacity drops from 220 kA at 240 V to 17 kA at 690 V — the high-end rating at 240 V suits transformer-secondaries or high-fault commercial services, while the 690 V figure still clears most industrial motor-circuit faults. Thermal derating is flat at 40 A from 40 °C through 50 °C, then steps down to 37 A at 70 °C. That's a tight derating curve; you don't lose much headroom in a warm panel.
Mounts on DIN rail or direct-panel via the SENTRON base adapter.
